Now that ebrary has the ability to download ebooks, the University of Toronto Pres has decided to pull its ebooks from all subscription collections.
What does this mean? Where we have purchased a copy of a U of T ebook, we retain access. Where we only subscribe to a collection that has a U of T ebook in it, we lose access to the ebook. This covers over 570 and it will take a while for the UBC Catalogue and Summon. So, please be patient, but do keep reporting any ebooks you can’t access.
