Yours to keep
Free means free
No account, no catch, no small print. These books are old enough that they belong to everyone now, or they come with an open license that welcomes exactly this — so reading them, saving them, and sharing them is simply what they are for.
Read one tonight, download the lot, print a stack for a classroom, hand a copy to a friend. It is all yours to do, and always free.
Formats & downloads
Yes — take them with you
Every book is free to download, with no account and no email address. Open a book above and the download options are on its page. The files are yours: keep them, copy them, hand them to someone else, put them on a school server.
A file on your phone, a trip to a print shop, and the price of the paper — that is a real book on your desk, black and white and bound. Nothing here needs anybody’s permission to print: it is public domain, or it carries a license that says so outright.
- Read in the browsernothing to install
- PDFevery title
- EPUBphones & e-readers
- Imposed-sheets PDFcut & stack, tabloid
Not every title has every format yet — open a book and its page lists what it has. The imposed-sheets PDF is the one the program is built around: two book pages to a side on large sheets, so a local press or a copy shop can print, cut and bind it into a real book.

Read the book. Then take the free course.
Nydus Foundation also runs Nydus Open Learning, a free learning platform with courses from early math to test prep. Pick a subject, start at whatever level suits you, and go at your own pace. There is nothing to buy, no trial that runs out, and no email needed to start.
