Google Books: Previews are available for some books.
Internet Archive/Open Library: Non-profit library of millions of free books, movies, software, music, websites, and more.
If the book is not available at Barry, and is available at a Southeast Florida Library Information Network (SEFLIN) member library, current Barry students, faculty, and staff are allowed to check out the book from most SEFLIN member libraries. All you need is a SEFLIN card (the card is available at the circulation desk) and your current Barry ID.
If you are unable to visit a SEFLIN Member Library, you also have the option to request the book using interlibrary loan service.
