Books on the site not in the public domain (most books published since 1925) are nearly all at the Internet Archive, so you will need a free account there to read them. Here’s their info about borrowing books.
Many books in Internet Archive are no longer available for borrowing, but short entries for removed books still appear in search results. The short entry for a removed book shows Source: removed beneath the title. You can filter these out in the Internet Archive search results pages. In the left column, go to Collection and click Texts to Borrow. Note that this also will filter out all the older books that are now in the public domain.
