Sorry, stuck at work and just posting on my phone.<br/><br/>The spell lets you look for a general object and find the nearest one.  I'll say the catalog's description is enough for that, but there's no guarantee it's Zitka's and not someone else's.  You can also look for a specific item, but that requires seeing it firsthand.<br/><br/>Also, I assume the characters know more than the players for some things, so Gered does know that the spell might not point him in the right direction.  If you want to change your mind, go ahead.
