I was a good girl though and only borrowed 13 books.

Great googly moogly, the local libraries now lets you take out 25 items at a time. Twenty-five. I have no idea how someone would be able to go through all of them in a mere 4 weeks. I can remember when you were only allowed 6 books over a 2 week period! And I still had trouble finishing them all and getting them back on time!
