O'Reilly Free With a Library Card: Which Libraries Offer It and How to Sign In

O'Reilly's platform of technology and business books, videos and courses is offered by many public libraries to their cardholders. The Seattle Public Library, for one, describes its online resources as free research tools you use with your library card. Libraries call it O'Reilly for Public Libraries, O'Reilly Complete Public Library or O'Reilly Tech eBooks & Courses. How you sign in, and what works once you are in, depends on the library: Mount Prospect asks for your card number and PIN, Seattle offers it on the website only, and Knox County shares one account among thousands of users. Use the finder below to check yours.

O'Reilly library access finder

Choose your library, and if you like, one thing you want to do. The finder shows the name your library uses, how you get in and what its page says, plus a plain answer on the feature you picked, taken from the library's page or O'Reilly's own help pages.

Your answer will show here.

Library details checked September 28, 2026. Features can change when a library renews its subscription, so the library's own page has the final word.

Libraries that offer O'Reilly with a card

We read the O'Reilly page of each library below. Six of the eight call the product O'Reilly for Public Libraries; Seattle and Santa Clara County use their own names.

From each library's own page, read September 28, 2026 (Santa Clara County from an Internet Archive copy made September 14, 2026). Many other libraries offer O'Reilly too; look for it in your library's databases or online resources list.

What the library version includes

O'Reilly's help center describes the full platform as 60K+ book titles from O'Reilly and nearly 200 other publishers, 30K+ hours of instructor-led courses and recordings, 3K+ audiobooks, and early release titles, which are O'Reilly books still in progress. It also says that not every book is on the platform, because publishers license titles at their own discretion.

Library pages quote their own numbers, and they do not all match:

  • Florham Park Public Library lists 50K+ titles, including O'Reilly books in early release, 30K+ hours of video, case studies, learning paths and expert playlists, with nearly 1,000 topics in technology and business.
  • The Seattle Public Library quotes nearly 50,000 titles, including 7,000 videos about computing, databases, programming and web design.
  • Knox County Public Library lists 35K+ books, 30K+ hours of video, learning paths, case studies, interactive tutorials, audiobooks and O'Reilly conference videos.
  • Mid-Continent Public Library describes thousands of business and technology books you can read online, covering finance, human resources, management and marketing on the business side, and web administration, programming, certification, Windows, Java and Linux/Unix on the technology side.
  • DC Public Library names publishers such as O'Reilly, Sams and Microsoft Press, and Santa Clara County adds Cisco Press, Adobe Press, John Wiley & Sons, Apress and Pearson Certification.

Florham Park and Santa Clara County both mention early release titles. For free coding courses beyond O'Reilly, see our guide to free coding classes at libraries.

How to sign in with your library card

O'Reilly runs a library access page that opens with one line: get instant access through your library. Its help center explains the rest. Enter the name of your school or institution, click Sign in and follow the instructions on screen. Depending on the institution, you are sent to its login page or asked for your affiliated email address.

Each library in the table links to O'Reilly from its own page, so starting there is the safer route. The details differ:

  • Mount Prospect Public Library asks for your 14-digit card number, printed on the back of the card, and your PIN. Unless you changed it, the PIN is the last 4 digits of your phone number.
  • DC Public Library marks it library card required and lists teens and adults as the audience. Knox County lists the same two audiences.
  • Anne Arundel County Public Library files it as a Library Exclusive resource.
  • Florham Park Public Library says a library card or registration is not required for access, the only library in this finder that says so.

If your library is not listed in the finder, search its databases list for any of the three names in the table. The same card often opens other learning services, such as Udemy through Gale.

What works in a shared library account

Knox County Public Library is candid about the limits. Its O'Reilly account is shared by thousands of people, so some personal features do not work for public library users, such as the "your O'Reilly" page, settings and apps. Its page spells out what that means day to day:

  • No downloads. The ebooks and videos are not downloadable. Books are fully searchable and always available, with no on-hold waiting.
  • Notes do not last. Highlights, notes and history stay only for the session and are then deleted.
  • Bookmarks help. A browser bookmark set while you read takes you back to the chapter you were in, so note or screenshot the exact spot. A link you email yourself with the share button opens the start of the book instead.
  • Playlists can be kept. A public playlist is saved, but a private one is wiped at the end of the session. Before you leave, open the playlist's share settings and share it with the library. Knox County users can find each other's playlists under Explore, then Shared playlists, then Discover, then Your Organization.

Seattle has a similar limit: it lists O'Reilly Complete Public Library as website only, not available via app. That matters because O'Reilly's help center says content can be downloaded for offline use only in its mobile app, and a laptop or desktop needs an internet connection. O'Reilly adds that Kindle devices and most other e-readers cannot install its app. If you study on a train or a plane, check your library's rules before you count on offline reading.

Library access or O'Reilly's free trial

If your library does not offer O'Reilly, the company's own trial is the other free route. Its help center says no credit card is needed to sign up and the trial cancels on its own after 10 days. That suits a short project, such as reading one book before an interview.

None of the eight library pages mentions a time limit. O'Reilly says there is no time limit on reading a book while the subscription is active, and the time shown next to a title is only an estimate of how long it takes to finish. At a library, the subscription is the library's: Knox County says its access was purchased through the Shelton Bequest and the Friends of the Library. The shared account limits above are part of that deal where a library uses one. Our online learning guide covers the other course platforms libraries offer.
