Project Gutenberg

Project Gutenberg is the grand daddy of free ebook web sites. Started by Michael Hart in the 1970s the original collection was a small assortment of books that Hart hand typed in order to digitize classic works of literature. Since then the project has grown enormously and now contains 33,000 books and documents in the public domain. You won’t find a larger or better organized collection of classics anywhere on the internet.

All the books at Project Gutenberg are free, legal, and available as ePub, Kindle, HTML, and basic text documents.

ManyBooks.net

If you like the idea of Project Gutenberg—a massive index of public domain books—but you’re not a fan of their Spartan interface and text-only listings, then ManyBooks is for you. ManyBooks is essentially a Project Gutenberg mirror with some extras layered on top. Those extras include detailed entries for each book with summaries, cover art, book reviews, and books formatted in over 20 digital formats.

If you’re looking for the Project Gutenberg experience with more of a modern digital bookstore feel and flair, ManyBooks.net is it. All the books are free and formats include LIT, LRF, ePUB, MOBI, PDF, and more.

DailyLit

DailyLit takes a novel approach to ebooks. Rather than offer an entire book for instant download, they’ve essentially modernized the idea of the serialized novel. In decades past magazines and newspapers would print books, almost always popular fiction, in serial form breaking the book up into small segments. The publication’s readers were able to enjoy the book and the author was paid a lump sum by the publication. DailyLit takes that model and applies it to email and RSS. You pick out a book, they send you a chunk every day, and you read and enjoy it with a small bit of advertising attached.

They solve two dilemmas which this arrangement: how to get commercial books in front of people for free and how to fit reading into a busy schedule. It’s not a perfect solution for everyone but the books are free and the topics diverse. DailyLit currently features a selection of around a thousand books.

FeedBooks

FeedBooks has a regular ebook storefront, but the part we’re interested in is their public domain and original books sections. Between the two they have thousands of novels, short stories, and poetry collections. It is one of the smaller collections in our roundup but we’re not going to complain—free but small is still free.

All FeedBooks ebooks are in ePUB format.
