You can find the stable book link under the image of the cover. Just click on Share Link to Book.
A box with the link will pop up. Copy that link:
If you are off-campus, this link will NOT take you to the ebook. However, you can add the library proxy prefix to the beginning of this URL. The resultant link should look like this:
https://vanguard.idm.oclc.org/login?url=https://ebookcentral.proquest.com/lib/vusc-ebooks/detail.action?docID=6232885
Be sure to remove any spaces between the prefix and the stable URL.
NOTE: You can also link to a specific location in a book.
Navigate to the appropriate page, and click the link icon ( ) near the top of the page. This will bring up a similar pop-up box with a link. Copy that link and add the library proxy prefix as instructed above.
