I feel the need to explain panel #4. For those of you that haven't worked in a library or don't use a system like ours, an NOS occurs when a book requested by a patron or staff cannot be found for one reason or another. NOS stands for Not On Shelf...and we indicate that on a slip and fax it to the appropriate retrieval desk. As funny as some of these songs are, I can't take credit for the 2nd and 4th panel of this cartoon. I tried to do some research as to who thought of these great songs, but from talking to fellow co-workers, it sounds like they're collective ideas that developed over the past few years and can't be pinned down to just one person.
I'm posting this cartoon before heading out for a quick visit to the Southwest.
In the meantime, if you're interested in ordering my cartoon zine online, it's available at Powell's Books and you can get it here.
