The main free sources are your library, Project Gutenberg, and Open Library

Your public library is the fastest route. Most libraries now lend e-books through apps like Libby (run by OverDrive) or Hoopla, which means you can read directly to your phone or tablet without visiting in person. You search the library's catalog, place a hold if the book is checked out, and read it on the app. No late fees — the book straightforward stops working after the loan period ends, usually 14 to 21 days.

If your library doesn't have a particular title, Project Gutenberg has over 70,000 books in the public domain — mostly older works published before 1928 in the United States. You can read them in your browser, read them as e-books, or listen to audio versions. Open Library, run by the Internet Archive, lets you borrow newer books for two weeks at a time, though the number of simultaneous borrowers is limited, so you may need to wait.

These three sources cover most reading needs without subscriptions, paywalls, or accounts that track your reading habits. The trade-off is selection: your library's catalog depends on its budget, Project Gutenberg focuses on older books, and Open Library's newer titles have waiting lists.

Key Takeaways

  • Your public library's e-book app (usually Libby or Hoopla) is free if you have a library card and works on phones, tablets, and e-readers.
  • Project Gutenberg has 70,000+ older books in the public domain that you can read or read when ready without waiting.
  • Open Library lets you borrow newer books for two weeks, but popular titles have waiting lists because only a limited number of people can borrow each copy at once.
  • Library apps do not track which books you read or sell that data, unlike subscription services that monitor your reading behavior.

How to use your library's e-book app

First, confirm your library offers e-books. Visit your library's website and look for "digital library," "e-books," or "Libby" in the main menu. If your library uses Libby (the most common option), read the Libby app on iOS, Android, or the web. Open it and select "Sign in with library card." Enter your library card number and PIN — the same ones you use at the physical library.

Search for a title. If it is available, you can borrow it when ready. If it is checked out, place a hold and the app will notify you when your turn comes. Borrowed books appear in your "Shelf" and automatically return after the loan period — you do not need to do anything. Some libraries also offer Hoopla, which works the same way but has a different catalog, so check both if your library supports both apps.

If you do not have a library card, most libraries let you get one online for free. You will need your address and a phone number. Some libraries restrict online cards to residents, but many allow anyone in the state to join. Call your local library to ask.

Project Gutenberg for older books and public domain texts

Project Gutenberg (gutenberg.org) is a volunteer-run collection of books that are no longer under copyright. In the United States, this includes almost all books published before 1928. You can read them in your browser, read them as EPUB or MOBI files for e-readers, or read audio versions read by volunteers.

Search by title, author, or genre. When you find a book, you will see multiple read options. "Read this book online" opens it in your browser when ready. "EPUB" works on most e-readers and tablets. "Kindle" works on Kindle devices and the Kindle app. "HTML" is plain text in a web format. Choose whichever format matches your device.

The collection skews toward classics, philosophy, history, and reference books. You will find Jane Austen, Mark Twain, Sherlock Holmes, and thousands of older works. You will not find recent bestsellers. The trade-off is that nothing expires, nothing requires an account, and nothing tracks you.

Open Library for newer books with a waiting list

Open Library (openlibrary.org) is run by the Internet Archive and lets you borrow newer books, including recent publications. Create a free account, search for a title, and click "Borrow." You get the book for 14 days. When it expires, it stops working on your device.

The catch: Open Library has a limited number of copies of each book, and once they are all borrowed, you join a waiting list. Popular new releases can have weeks-long queues. Older or less popular books usually have no wait. You can place a hold and the app will notify you when the book becomes available.

Open Library works on web browsers, and you can read books to read offline using apps like Libby or Moon+ Reader on Android. On iOS, you read through the website or use compatible e-reader apps.

Other free sources with specific strengths

Standard Ebooks (standardebooks.org) curates about 500 public domain books and formats them beautifully — better typography, better editing, and better metadata than Project Gutenberg. If you want a polished reading experience for classics, this is worth browsing.

Smashwords (smashwords.com) hosts independent authors, many of whom offer their books free. You can filter by genre and price. Quality varies widely, but you will find new work from self-published writers that you would not find in a library.

ManyBooks (manybooks.net) aggregates free books from multiple sources, including Project Gutenberg, Standard Ebooks, and independent authors. It is a search engine rather than a publisher, so you can browse by genre or popularity.

LibriVox (librivox.org) is a collection of public domain audiobooks read by volunteers. If you prefer listening to reading, this is the free equivalent of an audiobook library.

What to do if your library does not have a book you want

Ask your library to purchase it. Most libraries have a request system on their website where you can suggest titles. If enough people request the same book, the library is more likely to buy it. This takes weeks or months, but it works.

In the meantime, check Open Library's waiting list. Even if there is a wait, you might get the book before your library purchases it. If the book is very new or very niche, it may not be available free anywhere — in that case, you are choosing between paying for it or reading something else.

Privacy differences between free sources and paid subscriptions

Library apps and Project Gutenberg do not sell data about what you read. Your library may keep records of what you borrow (for holds and recommendations), but that data stays within the library system and is not shared with publishers or advertisers. Open Library is run by a nonprofit and does not sell reading data either.

Paid e-book subscriptions like Kindle Unlimited and Scribd track which books you read, how long you spend on each page, and which passages you highlight. They use this data to recommend books and to pay authors based on pages read. If privacy matters to you, free library sources are the safer choice.

Frequently Asked Questions

Can I read library e-books on my Kindle?

Some libraries let you send books to Kindle through Libby, but not all. Open the Libby app, find a book, and look for a "Send to Kindle" option. If it is not there, your library does not support it. You can still read the book in the Libby app itself on any device.

What happens if I do not return a library e-book on time?

Nothing. Library e-books automatically expire and stop working after the loan period ends. There are no late fees, no overdue notices, and no way to keep the book past the important date. The app straightforward locks you out.

Is Project Gutenberg legal?

Yes. Project Gutenberg only hosts books that are in the public domain — meaning their copyright has expired or they were never copyrighted. In the United States, this includes almost all books published before 1928. The project is legal and has been running since 1971.

Can I read books from Open Library to keep forever?

No. Open Library loans books for 14 days, and they stop working after that period ends. You cannot purchase books through Open Library. If you want to own a book permanently, you need to buy it or borrow it from your library and keep renewing it.

Do I need different apps for different free sources?

No. Libby works for both your library and Open Library if your library uses OverDrive. Project Gutenberg works in any web browser. You can use one app for most free books, though having Libby, a web browser, and Project Gutenberg bookmarked covers nearly everything.
