Is there a way to upload several books to a Books from the Catalog box at once?
At this time, there is no other way to add books to a Books From the Catalog box than one at a time.
If you'd rather, you (or someone at your library/institution) could create a script that creates a list of books from your catalog and formats it however you'd like. That script would need to live on a server at your library/institution. Then you can use a Remote Scripts Box to pull that information into your LibGuides system.
Does anyone out there have any other ideas to share on adding items to the Books from the Catalog box? Scripts to share/discuss? Please add comments! :)
