OPAC allows you to perform parameter-based searches on the library's database to locate books by title, publisher, release year, etc., physical location within the library and their availability. There is also a 'book of the month' (normally famous or award-winning) which can help heaps with not only reading logs and English work but also general reading. Of course, you also have the option of speaking with one of the Librarians who can clarify things further and provide more information.
