On ProQuest eBook Central, staff have access to the full catalogue of 1.8 million books. These will appear in your search results. If the Library doesn't own a book, then you can only see a preview of it - you get to read online for 5 minutes at a time. The Library gives staff access to the full catalogue so that staff are able to suggest books for purchase.
To include only books owned by the Library in search results, either:
On the search results page, in the Refine Results column, click Visible and then tick the box next to Visible
Or, in the Advanced Search option, scroll down to Refine Options and tick the Visible box
