- WorldCat Discovery
- Group catalogues such as https://picarta.on.worldcat.org/
If you have found a title in your libraries' Discovery or in a Discovery group catalogue and would like to view other editions and formats, you can do this using the Explore Editions and Formats drop down menu.
This feature shows you whether other editions or formats of the same title are held by other libraries. You can use this feature, for example, when you wish to request a book using WorldShare ILL and the edition you initially found is not held by any libraries near you.
