"Borrowing" a book just means you can view it on the clunky web reader for one hour? Other online librarians (for the lack of a better word) like Proquest lend books using the Adobe Digital Editions platform, I think that would have been a better approach.

Edit: So it appears OpenLibrary does lend through ADE, but this feature is not applicable for all borrowable books. Some can only be borrowed for one hour, at least in this redesign.

There are multiple options for borrowing, depending on the title, including Adobe Digital Editions for applicable titles.
