Visit the Library from the Comfort of Your Own Phone

It mentions Internet Archive:

> The Internet Archive hosts millions of digital videos, audio recordings, images, books and old software programs, and LibriVox hosts public domain audiobooks.

But if you want a reading focused experience, with to-read lists and integrations with Librivox and Standard Ebooks, then you might want to check out their sister project Open Library rather than go direct to the Archive.
