You can search for books directly from the library home page. There is a selection button to search all books, which will look for physical and electronic versions, or for just ebooks.You can also search without making a selection, and narrow by format on the search results page.
The Library ebooks collections page includes information about the many ebook collections available to you through the Library. It also includes information on downloading, which can be tricky because the process varies among different platforms and publishers.
