Search both Ebooks and Print Books using Summon: if you have only used the library catalogue to search for titles, double-check our ebooks using Summon "More Search Options" then limit the "Content Type" to show only "Books / eBooks."
Inter-Library Loans: request the book through RACER/VDX; this allows you to search for books from university libraries across Canada or from selected International collections.
Worldcat.org: A quick way to search many GTA academic libraries, as well as the Toronto Public Library system, is to use worldcat.org. This search portal is the "world's largest network of library content and services" and allows you to search for books by title, subject or author. When you find a book, click on the title to view the record, the scroll down and add your postal code. Worldcat will show you the closest library that has a coy of the book.
Don't forget Internet Archive! With millions of open access (OA) books, audio files, videos, software, the "wayback machine" and more, Internet Archive is a significant research tool. Most of the over 2 million books are in the public domain--so published 75 years ago from the current date--; however, more and more current OA books, monographs, anthologies are being uploaded. It works especially well for OCAD U print reference books which cannot be signed out over night by undergraduate students. Always check Internet Archive, as OCAD U has digitized over 300 books for this portal.
