Once you complete the Mages Guild questline, you are granted the Eidetic Memory. In a recent update, discovery of a new Eidetic Memory book started generating the "Lorebook Discovered" notification, which is exactly the same notification that you get when you pick up a true Shalidor's Library "Lorebook" that advances the Mages Guild skill line. This generates confusion, as Eidetic Memory books do not progress the skill line like the Shalidor's Library Lorebooks do.

Eidetic Memory never used to generate a notification when a new book was found, so this could just be reverted. If it was decided that a notification is required to indicate that it's a new book, please consider changing the notification to "Eidetic Memory Updated". This will alleviate the confusion over the dual purpose of "Lorebook Discovered", as that would be returned to solely notifying you of new Shalidor's Library books and an increase in Mages Guild reputation.
