I have noticed in L4 that multi-volume resources can now be accessed and searched as a group, instead of individual volumes. THANK YOU!!!!
But, I have noticed that not ALL multi-volume resources behave this way. For example, Luthers Works do not behave this way, and several commentaries do not behave this way.
Please check to make sure that all multi-volume resources are programmed to behave as a group, especially when dragging from the library into a layout panel, or a collection.
Thanks!
