What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
For free books online, start with the kind of access you want: Project Gutenberg and Standard Ebooks offer public-domain classics; Libby connects you to your public library’s ebook and audiobook collection; OpenStax specializes in textbooks; and Google Books includes some free full books alongside previews. Other options focus on scholarly works, research, or audio. A free title may be a permanent download, a browser read, or a time-limited loan—not all three. Updated October 5, 2026.
This is an editorial selection, not a ranking. Availability, formats, and eligibility depend on the title, service, library, and country. Check the book’s own page before reading or downloading.
Choose a source by the kind of book and access you need
- Classic literature to keep: Project Gutenberg or Standard Ebooks.
- Newer books and audiobooks through a library: Libby, if your library participates and you are eligible for a card.
- Textbooks: OpenStax.
- Scholarly or research books: DOAB, HathiTrust, National Academies Press, or Library of Congress digital collections.
- Public-domain audio: LibriVox.
- A specific title or a way to discover one: Google Books, Open Library, or Internet Archive; check whether the result is a preview, a loan, or an unrestricted file.
Before choosing, check the title’s access model, available format, any account or library-card requirement, loan period or waitlist, and whether the work’s copyright status permits access where you live.
12 legal places to read or get free books
1. Project Gutenberg — public-domain classics
Project Gutenberg is a direct starting point for older books whose US copyright has expired. You can read many titles online or download them in supported formats. Its homepage showed 79,536 ebooks on October 5, 2026; that live catalog count changes and is not a promise that every title is available in every format. See its reading options to choose a format or device.

2. Standard Ebooks — polished public-domain editions
Standard Ebooks offers volunteer-produced editions of public-domain books, with attention to proofreading and consistent formatting. It is worth checking when you want a carefully prepared edition of a classic rather than simply the first available file.
3. Libby — your public library’s ebooks and audiobooks
Libby is a free app for borrowing ebooks and audiobooks from a participating public library. A library card and geographic eligibility may be required; particular titles can have waitlists or loan rules set by the library. Selected books can be downloaded for offline reading, but a library loan is temporary access, not an unrestricted permanent copy.
4. Open Library — catalog search and eligible loans
Open Library’s borrowing FAQ describes some digitized books as loans to one patron at a time. Eligible loans can be read in a browser and are usually offered in PDF or EPUB, subject to the book’s availability and borrowing terms. A loan is not the same as a permanent free download. The catalog also points readers to trusted book providers; check the specific provider and title page for access details.
5. Google Books — free full books and discovery
Google Books identifies free titles that include public-domain works, books made free at a rights holder’s request, and copyright-free material such as US government documents. Google advertises more than 10 million free books, but that is its own service-wide figure, not an independently audited count of downloadable titles. A search result may be only a preview, so confirm whether the book is fully readable or downloadable on its page.
6. OpenStax — free textbooks
OpenStax publishes peer-reviewed textbooks for students and instructors. Its books are available to access online or download as PDFs. It is a specialized textbook source, not a general fiction catalog.
7. LibriVox — public-domain audiobooks
LibriVox distributes free recordings of public-domain texts read by volunteers. Its public-domain guidance is based on US law and advises listeners elsewhere to check whether a work is public domain in their country. Audio availability does not itself establish the work’s copyright status in every jurisdiction.
8. Internet Archive — digitized books and lending
The Library of Congress ebook guide points to Internet Archive as a resource for digitized books. Access varies by item: some records provide open files, while others have lending controls. Use the item page to identify which applies rather than treating every catalog entry as a permanent download.
9. HathiTrust Digital Library — research collections
The Library of Congress lists HathiTrust among its external ebook resources. The digital library is useful for research and finding digitized books, but full-text and download access may depend on the work’s rights status and your eligibility.

10. Directory of Open Access Books (DOAB) — scholarly books
The Library of Congress ebook guide also lists DOAB, a discovery service for scholarly open-access books. It is a better fit for academic reading than for popular commercial titles. Follow the book or publisher link to check the license, format, and any conditions on reuse.
11. National Academies Press — research and policy books
The Library of Congress guide describes free PDF downloads from National Academies Press. It reports nearly 10,000 titles, but that figure is guide-era and should not be treated as a current catalog count. Check the individual book page for current access and format.
12. Library of Congress digital collections — books and library publications
The Library of Congress ebook guide identifies public-domain books and Library of Congress publications among the available resources. Access and download steps vary by collection, title, and user eligibility; consult the specific digital item page for its terms and formats.

Free access comes in several forms, and the distinction matters if you want to keep a file, read offline, or reuse a text.
- Public-domain download: A book whose copyright has expired in the relevant jurisdiction may be offered as a lasting file. Project Gutenberg and Standard Ebooks focus on public-domain editions; LibriVox applies a US-based public-domain approach to its recordings.
- Rights-holder-authorized free book: A publisher or author may make a title free. Google Books includes some titles made free at a rights holder’s request.
- Open textbook or open-access book: Educational and scholarly works may be available online or as a download. Check the book’s license for any reuse conditions; access does not automatically mean every use is permitted.
- Library loan: Libby and some Open Library titles provide borrowing for a limited period or while a copy is available. A loan is not an unrestricted permanent download.
- Preview: A service may let you view selected pages without making the complete book free. Google Books results can include previews, so verify the access shown for the title.
How to check a title before you read or download it
- Open the book’s own page. A search result or catalog listing is not proof that the full book is free or available to download.
- Identify the access model. Look for language indicating a permanent file, online reading, preview, or borrowing. For loans, note the due date, waitlist, and renewal rules.
- Check formats and device support. Confirm whether the title is offered in a browser, PDF, EPUB, audio, or another format your device can use. Project Gutenberg documents multiple reading options, while Open Library says eligible loans are usually available in PDF or EPUB.
- Check eligibility and location. Library collections can depend on your card and local library. Copyright status also varies by country and title; do not assume a US public-domain status applies where you live.
- For open-access books, inspect the license. Follow the book or publisher link and check what the license allows, especially if you intend to adapt, redistribute, or use the material commercially.
Do you need an e-reader?
No. A browser or phone app is enough for many services, and Libby can download selected library titles for offline use. A dedicated e-reader is optional if you prefer reading downloaded, compatible files on its screen. Check both the title’s format and your device’s compatibility; not every book works on every reader, and library titles are not supported on every model.
