In the page that opens, click on the Access button.
There are two options: you can either download it as a PDF (which is much easier) or read the book online.
Accessing the Print Book
The book is available at the E.J. Pratt Library in the reference section on the first floor. When you enter the library, turn right. The reference section is in the main reading room and the book is located under the call number BL80.3 .W69 2009.
Please note that the encyclopedia can not be taken out of the library.
