[Koha] Holds

I've searched the manual, but it appears that there's no provision for automatic staff notification whenever a patron places a hold on a title. Is this true? Lacking that feature, the "Holds to pull" report has to be checked periodically, correct? I'm also unclear on the purpose of the "Holds queue" report. Can someone clarify? I have a couple of titles in the queue, but can't remember how they got there, or how to get them off ... Thank you, Cab Vinton, Director Sanbornton Public Library Sanbornton, NH
