How not to search at a library

Zachary loves the Frisco Public Library, especially the children's section. The previous visit, the board book section had lots of favorites on the front row. Y'know- the classics: Thomas, Max and Ruby, monster trucks. This visit, a lot had been moved or checked out. So- I told Zachary we will have to go over to a catalog terminal to search. When we walk out of the children's section towards the terminal, Zachary starts yelling, "Max! Ruby! Where are youuuuuuu?" Hmm the books did not respond...
