People usually agree that checking your credit report regularly is a good idea, but after downloading all my credit reports just now I found out that I had overdue library fees of $40 from my old city and they sent me to collections! I am 99.9% sure I returned them. I received no mail notices and have received no phone calls from any collection agency either. It’s dated April 2008, although I’ve opened several bank accounts, brokerage accounts, and credit cards since then with no indication that my credit was anything but flawless. It’s only on my Experian report as well.
I’ll have to follow up on this later. Meanwhile, for you library users, I found this NY Times article Late Library Books Can Take Toll on Credit Scores. Well, not a big toll… 😛
