I'm curious about what other libraries have for cell phone use policies, if any. Ours has a No Cell Zone sign at the front entrance. People receiving calls usually head out to the lobby, but occasionally will just take their calls at their table, or hide in a bookstack or stairwell.
I've done it too.
I think that banning cell use is stupid in a library setting, UNLESS you have a silence policy or somesuch (we don't in our reference area). But what do others think?
