Library book

I got this book from the library last week as I wanted to read about the history of the Leeds Liverpool Canal. The first date stamped in it is 8 May 1991. It's almost 30 years old and it's obviously been read or looked at many times as there are 5 pages of stamps. The last time it was taken out according to the stamps is 22/08/2011 this may be wrong if it's been taken out and used the barcode. I loved the picture of the frozen canal and the ice breaking boat.
