Almost the same thing happened about 10 years ago. I had 4 library books and they too got packed up in a move and stored away. I realized I still had them and I did return them to the library. This time it was local. It was only $6.00 to return books I had for about 10 years. Apparently there is a limit on the fees. Thank God for that!
Since then I have had no issues with books getting packed away that belong to the library. The issue now is just having enough time to read the books I checked out. Right now I am in the very middle of the new Stephen King book, 11/22/63. It is due in a few days and I know that I will not finish it on my due date. I will keep it till I am due and will incur those fees. I was on a waiting list...number 69 when I began to read it. I finally got it and I already went on line to renew and it has a hold. So...there are many others still waiting on this book. I will be reading fast and furious till I get to the end. I hope to be done with it by the weekend so that I can pass it on! I guess I better get to reading and do less blogging!
