1. What Liibro Publishes
Liibro publishes independent educational digital guides created with the assistance of artificial intelligence. Every guide is compiled from published research, manufacturer guidance, public standards and general subject knowledge, and is provided for general educational and informational purposes only.
Nothing in any guide, or anywhere on this website, constitutes professional mechanical, electrical, medical, safety, legal or financial advice. No statement here has been evaluated by any regulatory authority. Liibro is not affiliated with, endorsed by or associated with any manufacturer, utility, retailer, trade body or public agency, and no brand name that appears in a guide implies any relationship with its owner.
2. Doing The Things We Describe
Some of our guides describe tasks that carry real physical risk — work involving electricity, combustion, fuel gas, pressurised systems, water, heights, tools, vehicles, machinery or open water. You undertake any hands-on task described in any of our guides entirely at your own risk.
You are responsible for following the relevant manufacturer's documentation, your local codes, and current safety guidance. Certain work is restricted by law to certified or licensed professionals in most jurisdictions. Always consult a qualified professional when in doubt, never disregard professional advice because of something you have read in one of our guides, and never bypass or defeat a safety device.
3. Results
Where any material mentions savings, service life, durability or results — including any figure in a guide's title — these are illustrative and aspirational, not promises. Individual results vary depending on the equipment or subject in question, its age and condition, the circumstances of use, and how closely the guidance is followed. Some situations will not improve regardless of care.
Any prices quoted are ranges gathered from public cost surveys at the time of writing. They are not quotes, and they are not offers.
4. Guide-Specific Notices
The sections below apply in addition to everything above, to the guide named in each.
The 30-Year HVAC Bible
Heating and cooling equipment involves mains electricity, combustion, fuel gas and pressurised refrigerant. Work on refrigerant circuits requires federal certification in the United States and there is no exemption for a homeowner working on their own house; work on gas piping and gas valves is separately licensed almost everywhere. This guide explains where that line falls and repeatedly tells the reader not to cross it — that guidance is part of the product and following it is the reader's responsibility.
If you ever smell gas, leave the building immediately, touch no switch, and call your gas utility and emergency services from outside. Carbon monoxide has no smell; this guide is not a substitute for working carbon monoxide alarms, and nothing in it should delay anyone from calling their gas utility or emergency services.
Nothing in this guide is a diagnosis of your equipment, and no reading you take yourself replaces measurement by a licensed technician with proper instruments.
The 500K-Mile Car Care Bible
This guide is educational material about vehicle maintenance, written for a general audience and created with the assistance of artificial intelligence. It is not a substitute for your vehicle’s owner manual, its manufacturer service schedule, or a qualified mechanic, and it is not affiliated with, endorsed by or connected to any vehicle manufacturer, parts brand or repair chain named in it.
Working on a vehicle carries real risk. Jacking a car, running an engine in an enclosed space, and handling fuel, hot coolant, brake fluid, batteries and airbag components can cause serious injury or death. Never work under a vehicle supported only by a jack. Brake, fuel, airbag and high-voltage hybrid systems are not owner-serviceable and the book says so where it matters. Where any instruction here conflicts with your manufacturer’s documentation, follow the manufacturer.
Repair prices quoted are US market ranges at the time of writing and vary by region, vehicle and shop. Mileage figures describe what consistent maintenance can make possible, not a guarantee about any particular vehicle. You are responsible for deciding what work to attempt and what to hand to a professional.
The 360 Boat Care Protocol
This guide is educational material about boat inspection, maintenance and ownership costs, written for a general audience and created with the assistance of artificial intelligence. It is not a substitute for your engine and vessel manufacturer’s documentation, an accredited marine surveyor, or a qualified marine technician, and it is not affiliated with, endorsed by or connected to any boat builder, engine maker or marina named in it.
A pre-purchase inspection you carry out yourself is not a marine survey. Nothing in this guide replaces an accredited surveyor, and no result from a walk-around described here should be relied on for an insurance, finance or purchase decision on its own.
Boats carry inherent risk of drowning, fire, explosion, carbon monoxide poisoning and electric shock. Fuel systems, propane, exhaust and carbon monoxide, shore power and DC electrical work, hauling and blocking, and any vessel taking on water are jobs for a qualified professional. Carbon monoxide has no smell; nothing here is a substitute for working CO alarms aboard. Follow U.S. Coast Guard requirements and your manufacturer’s documentation wherever they conflict with anything written here.
Costs, service intervals, insurance practice and regulations reflect the United States market at the time of writing and change over time. Engine-hour figures describe what consistent maintenance can make possible, not a guarantee about any particular vessel.
The 10-Day Blackout Power Bible
The 10-Day Blackout Power Bible is an independent educational digital product created with the assistance of artificial intelligence. All content — the ebook and the website copy — is provided for general educational and informational purposes only and is compiled from published research, manufacturer guidance, and general knowledge of home backup power. Nothing in it constitutes professional electrical, mechanical, medical, safety, legal or financial advice, and no statement in it has been evaluated by any regulatory authority.
Electrical work carries a risk of death, fire and serious injury. Connecting any generator or battery system to a home's wiring is regulated work in most jurisdictions and is subject to local codes and inspection. Connecting a generator to house wiring without properly listed transfer equipment can energise the utility lines outside your home and kill a utility worker. Never attempt it. Where this book describes transfer switches, interlock kits, inlet boxes or panel work, it does so to help you understand your options and have an informed conversation — not to qualify you to perform the work. Any work on a service panel should be carried out by a licensed electrician and permitted and inspected where your jurisdiction requires it.
Engine-driven generators produce carbon monoxide, which is odourless and can kill within minutes. Never operate a generator indoors, in a garage, in a basement, in a crawlspace, or near any window, door or vent, even with doors or windows open. Follow the manufacturer's stated clearances and use working carbon monoxide alarms. Fuels — gasoline, propane and natural gas — are flammable and, in the case of natural gas and propane, can accumulate and explode. Never modify a generator's fuel system or improvise a gas connection.
Batteries can vent, overheat and cause fire if damaged, short-circuited, or charged outside their stated temperature range. Follow the manufacturer's instructions for the specific product you own, including fusing, cable sizing, ventilation and charging limits. Product names, specifications, capacities, intervals and prices mentioned anywhere in the book were accurate to the best of our knowledge at the time of writing and change without notice; always verify against the current documentation for your own equipment, which supersedes anything written here.
If anyone in your household depends on mains-powered medical equipment — an oxygen concentrator, a ventilator, a powered wheelchair, refrigerated medication or any other life-sustaining device — do not rely on this book, or on any backup power system, as your plan. Speak to your physician and your equipment supplier, and register with your utility company's medical priority programme where one exists. Backup power can fail.
Where any material mentions durations, savings, capacities or results — including the "10 days" figure in the title — these are illustrative estimates only. Actual results vary considerably depending on the equipment, the loads, the fuel available, the weather, the condition of the hardware and how closely the guidance is followed. No outcome is promised or guaranteed. All products sold are digital ebooks delivered by download.
The Million-Mile Motorhome Care Bible
The Million-Mile Motorhome Care Bible is an independent educational digital product created with the assistance of artificial intelligence. All content — the ebook and this website’s copy — is provided for general educational and informational purposes only and is compiled from published research, manufacturer guidance and general knowledge of recreational vehicles. Nothing in it constitutes professional inspection, mechanical, safety, legal, insurance or financial advice, and no statement in it has been evaluated by any regulatory authority.
This guide is not a pre-purchase inspection and does not replace one. It says so repeatedly and it names the inspection levels to buy and when, including the separate chassis inspection an RV inspector does not perform. No walkaround you carry out yourself should be relied on alone for a purchase, finance or insurance decision on a vehicle of this value.
Getting onto an RV roof, or under a coach, is how people are seriously injured or killed. The book deliberately teaches the roof and underside checks to be done from the ground, and where it says to hire somebody, that guidance is part of the product and following it is the reader’s responsibility. Never work under a vehicle supported only by a jack or by its own levelling system.
Hydraulic and electric slide-outs close with several thousand pounds of force and have no clutch and no pressure sensor. Propane, engine exhaust and generator exhaust all produce carbon monoxide, which has no smell and can kill within minutes; nothing here is a substitute for working carbon monoxide and propane alarms in the coach. House and chassis electrical systems, propane systems, brakes, steering and suspension are jobs for a qualified technician.
Prices, service intervals, engine and chassis specifications, tax and titling practice and dealer fees reflect the United States market at the time of writing and change over time; verify anything before you rely on it. Mileage figures — including the “million-mile” in the title — describe what consistent maintenance can make possible on some drivetrains, not a guarantee about any particular coach. All products sold are digital ebooks delivered by download.
The 30-Year Mower Bible
The 30-Year Mower Bible is an independent educational digital product created with the assistance of artificial intelligence. All content — the ebook and this website’s copy — is provided for general educational and informational purposes only and is compiled from published research, manufacturer literature and general knowledge of outdoor power equipment. Nothing in it constitutes professional mechanical, safety, legal or financial advice, and it is not affiliated with, endorsed by or connected to any manufacturer, transaxle maker, engine maker or dealer named in it.
Mower blades rotate fast enough to kill. Disconnect the spark plug lead and remove the key before going anywhere near a deck, a blade or a discharge chute, and never work under a raised machine or a raised deck that is not properly supported on stands. Exhausts and engine components stay hot long after shutdown; gasoline is flammable and its vapour more so; and lead-acid batteries can produce explosive gas and cause burns.
A riding mower can roll on a slope, and a rollover on a machine without a rollbar is frequently fatal. Where this book describes measuring your own ground and testing whether a machine holds on it, it does so to help you decide what is safe to mow and what is not — not to qualify you to mow ground the manufacturer excludes. Follow the slope limits in your own operator’s manual, which supersede anything written here, and use the seatbelt where a rollbar is fitted.
Model numbers, torque ratings, service intervals, warranty terms, fuel specifications and prices reflect manufacturer literature and the United States market at the time of writing and change without notice; verify anything against the current documentation for your own machine, which supersedes anything written here. Where any material mentions service life, savings, hours or cost per hour — including the “30 years” in the title — these are illustrative estimates only, and outcomes vary with the machine, the ground, the hours put on it and how closely the guidance is followed. All products sold are digital ebooks delivered by download.
The $0-Bill House Protocol
The $0-Bill House Protocol is an independent educational digital product created with the assistance of artificial intelligence. All content — the ebook and this website’s copy — is provided for general educational and informational purposes only and is compiled from published research, building-science literature, manufacturer documentation and general knowledge of residential construction. Nothing in it constitutes professional engineering, building, electrical, plumbing, geotechnical, environmental or legal advice, and it is not affiliated with, endorsed by or connected to any manufacturer, utility, contractor or trade body named in it.
Trenches kill people every year, and they kill them quickly. Call 811 or your national one-call service before any digging, without exception, and never enter an unshored trench deeper than five feet — not to adjust a pipe, not for a moment. Where this book describes digging, it describes work most readers should hire out to an insured excavator, and no depth, slope or soil description in it is a substitute for a qualified assessment of your own ground.
Attics in summer reach temperatures that cause heatstroke, ladders fall, and ceiling joists are not a floor. Work in the early morning, never alone, and keep your weight on the framing. Air sealing, ventilation changes and any work near a combustion appliance can affect how that appliance vents; where a house has gas, oil or a wood stove, have combustion safety and draft verified by a qualified technician after the work. Radon can concentrate in soil air, which is why this book tells you to test before considering any system that moves it — follow the guidance of your national radon authority, not this book.
Rainwater is not drinking water until it has been made so. Harvesting, storing and treating rainwater is regulated differently in every state and country, potable use requires treatment and testing that this book only outlines, and connecting any collected supply to household plumbing must be done so that it can never cross-connect with a public supply. Electrical work, panel work and anything permanently connected to house wiring is for a licensed electrician, under the code in force where you live.
Costs, product names, equipment specifications, permit rules, incentive programmes and code requirements reflect the United States market at the time of writing and change without notice; verify anything against your own local building department and current manufacturer documentation, which supersede anything written here. Where any material mentions savings, bill reductions, payback periods or temperatures — including the “$0” in the title, which names an aim and not a promise — these are illustrative estimates only, and outcomes vary enormously with the house, the climate, the ground, the utility and how closely the guidance is followed. All products sold are digital ebooks delivered by download.
The Scam-Proof Car Buying Bible
The Scam-Proof Car Buying Bible is an independent educational digital product created with the assistance of artificial intelligence. Everything in the ebook and on its sales page is provided for general educational and informational purposes only. It is not legal, financial, tax, insurance or mechanical advice, it creates no professional relationship of any kind, and no statement in it has been evaluated by any regulatory authority.
The book was written for buyers in the United States. Laws and practices covering vehicle titles, liens, sales tax and trade-in tax credits, dealer fees, financing disclosures, return rights, odometer statements and consumer remedies differ from state to state and change over time, and some of what the book describes does not apply outside the United States at all. Before you rely on any rule described in the book, confirm it with your state's motor vehicle agency, your state attorney general's consumer office, your lender, your insurer or a licensed attorney.
The inspection methods in the book are a first screening and are not a substitute for a pre-purchase inspection by a qualified, independent mechanic. No visual inspection, scan tool or history report can find every defect, and a vehicle that passes every check in the book can still have serious problems. Never get under a vehicle that is supported only by a jack, never reach into a running engine bay, keep clear of hot and moving parts, and do not test drive a vehicle you believe to be unsafe. Meeting strangers, carrying money and handing over a vehicle or its title carry real personal and financial risk; the precautions in the book reduce that risk and do not remove it.
All prices, repair costs, interest rates, payments and savings in the book and on the sales page are illustrative estimates and ranges gathered when the book was written. They vary by vehicle, region, lender and date, and they will change. No particular price, discount, saving or outcome is promised or guaranteed, and individual results vary. All products sold are digital ebooks delivered by download.
The Paid-Off Truck Playbook
The Paid-Off Truck Playbook is an independent educational digital product created with the assistance of artificial intelligence. Everything in the ebook and on its sales page is provided for general educational and informational purposes only. It is not legal, financial, tax, accounting, insurance, regulatory or mechanical advice, it creates no professional relationship of any kind, and no statement in it has been evaluated by any regulatory authority.
The book was written for owner-operators in the United States. Federal and state rules on motor carrier registration and operating authority, leasing, fuel and weight-distance taxes, apportioned registration, the heavy vehicle use tax, hours of service, emissions equipment, tolls, insurance minimums, repossession and deficiency balances, bankruptcy and taxation differ from state to state and change over time, and some of what the book describes does not apply outside the United States at all. Before you rely on any rule, figure or procedure described in the book, confirm it with the relevant agency, your lender, your insurer, a certified public accountant or a licensed attorney. Decisions about financing, leasing, factoring, insurance, bankruptcy or surrendering a vehicle should be made with a qualified professional who knows your own situation.
The inspection, maintenance and emissions-system methods in the book are a first screening and are not a substitute for work by a qualified heavy-duty technician. No visual inspection, computer report or oil sample can find every defect, and a truck that passes every check in the book can still have serious problems. Heavy trucks involve air-brake and spring-brake systems, tires and wheels at high pressure, hot exhaust and aftertreatment components, diesel fuel and diesel exhaust fluid, fifth wheels and landing gear, and vehicles weighing many tons. Never get under a vehicle that is supported only by a jack, never work on a wheel or brake you are not trained for, and never operate a vehicle you believe to be unsafe. Follow your equipment manufacturer's instructions and all applicable regulations.
All costs, rates, prices, fees, fuel prices, interest rates, tax figures and savings in the book and on the sales page are illustrative estimates and ranges gathered when the book was written. They vary by truck, lane, region, lender, carrier and date, and they will change. No particular rate, profit, saving, loan outcome or business result is promised or guaranteed, and individual results vary. All products sold are digital ebooks delivered by download.
100 Tricks to Make Your House Look More Luxurious and Twice as Big
100 Tricks to Make Your House Look More Luxurious and Twice as Big is an independent educational digital product created with the assistance of artificial intelligence. All content — the ebook and this website’s copy — is provided for general educational and informational purposes only. Nothing in it constitutes professional design, construction, electrical, plumbing, structural, financial or legal advice, and it is not affiliated with, endorsed by or connected to any manufacturer, retailer or brand named in it. Photographs and illustrations in the book are illustrative and many were generated with artificial intelligence; they are not photographs of real projects or of any reader’s results.
Ladders, power tools and light fixtures cause serious injuries every year. Use a ladder that is rated for your weight and set on firm, level ground, and never overreach from it. Turn the power off at the breaker and confirm it is off with a tester before touching any light fixture, switch or outlet; any new circuit, new wiring or work inside a panel is for a licensed electrician, under the code in force where you live. Before drilling into a wall or ceiling, check for pipes, wires and ducts behind it. Heavy mirrors, shelves, curtain rods and fixtures must be fixed into framing or with anchors rated for their weight.
Homes built before 1978 may contain lead paint, and older homes may contain asbestos. Do not sand, scrape or demolish painted trim, walls or ceilings, textured ceilings or old flooring in an older home until they have been tested; follow the guidance of your national environmental or health authority. Use paints, adhesives, stains and solvents with the ventilation and protective equipment their manufacturers require. Renters should get written permission from their landlord, and owners in a homeowners’ association should check its rules, before making any change described in the book.
Prices, product names, finishes and availability reflect the United States market at the time of writing and change without notice. Where any material mentions costs, savings, added value or how much larger or more expensive a room will look, these are illustrative estimates and personal judgments only; no increase in property value, sale price or appraisal is promised, and results vary with the house, the materials and how closely the guidance is followed.
The other books sold with it in the Home Trio and the Whole House Library — The $0 Household Bible, The $0-Bill House Protocol, The No-Fridge Pantry, 77 Forgotten Recipes From the Past and The Backyard Pest Defense Bible — are independent educational digital products under the same terms. Food preservation, canning, curing and storing food without refrigeration carry a real risk of serious food-borne illness, including botulism: follow current tested guidance from your national food-safety authority, which supersedes anything in these books, and discard any food you are unsure of. Recipes may contain common allergens. Any pest-control substance, homemade or bought, must be used exactly as its label and local law allow and kept away from children, pets, water and food. Traditional household methods described in these books are historical and educational, not medical, veterinary or professional advice. All products sold are digital ebooks delivered by download.
Clutter-Free Home Protocol
Clutter-Free Home Protocol is an independent educational digital product created with the assistance of artificial intelligence. Everything in the ebook and on its sales page is provided for general educational and informational purposes only. It is not legal, financial, tax, accounting, medical, pharmaceutical or safety advice, it creates no professional relationship of any kind, and no statement in it has been evaluated by any regulatory authority. The narrator and the household stories in the book are presented in the voice of the Betty Barlow’s Home channel.
Clearing and organizing a home involves bending, reaching, lifting and carrying, and falls and strains are a real risk, particularly for older adults. Never stand on a chair, a stool without a handrail, a ladder or a tub edge to reach anything; leave high shelves, attics, basements and heavy objects to someone able to do the work safely; fill boxes only partway; and anchor tall furniture to the wall with the help of a qualified person. Grab bars must be installed into wall studs or with anchors rated for the purpose, and a towel bar must never be used to support a person.
Dispose of expired or unused medicines, sharps, paint, solvents, batteries, propane and household chemicals only as your pharmacist, your local authority or the product label directs, and never mix cleaning products. Food storage and leftover guidance in the book is general; follow current food-safety guidance and discard anything you are unsure about.
Information about record keeping, wills, lists of personal property, estate sales, consignment, auctions, the value of household goods, storage units and hired services is general, varies by state and by provider, and changes over time. Whether a written list of belongings has any legal effect depends on the law of your state and on your will; consult a licensed attorney, a tax professional or a financial adviser about your own situation before relying on anything in the book. Never write passwords or full account numbers in plain view.
All costs, fees, prices, values and savings in the book and on the sales page are illustrative estimates and ranges gathered when the book was written. They vary by region, provider and date, and they will change. No particular result, sale price or saving is promised or guaranteed, and individual results vary. All products sold are digital ebooks delivered by download.
