Psych Pharmacy text books/resources

I am starting a new job in a psych hospital and was wondering if there are any books /sources that you recommend on psych drugs? for example, there was an order for Ativan IM for a pt who was on Zyprexa IM... I just dont want to miss any of those tricky situations... Ive worked in retain fro few years and did not have to deal with psych pharmacy in that aspect. Especially pediatric psych Any good books/sources for psych pharmacists?
