Limit Reached!

Yikes!  We went to the library today, and I had maxed out my card!  I felt like a shopper denied use of my credit card!
Now let it be known that our library allows 100 items checked out on a card.
I never really thought I'd have THAT many items checked out at once.
But, with a family of five....and now I'm homeschooling and using the library to the maximum (obviously!).  
Having all the items checked out on my card means that I can track due dates on-line.
I had to stop and think, seriously, do I have THAT many items out????  it is possible?
When the librarian said limit reached, I had just moments earlier returned a huge bag of items that had not yet been entered into the system as "returned".
Now I'm back home....
I just checked my account on-line, and joy of joys, I'm down to 79 items!
Oops, gotta run, I'm headed back to the library!!
