This isn't a reference question, but I think it is by far the most interesting email the library received this week. The message below was sent to my Director, and was then forwarded to our cataloger and me to look into:
Subject: former(?) Rare Chelmsford Library Book 1743 MASSACHUSETTS Bay COLONIAL Laws
Hello, I noticed this rare book for sale on ebay and an image shows an ownership label of your library. I'm not interested in buying it, just wanted to bring it to your attention in case this rare item had been removed from your collection. No response needed to me.
Wow. We checked out the ebay listing for this book, and sure enough, the inside cover has a old Chelmsford Library bookplate:
None of us ever recalled seeing this book in the collection, or even anything remotely like it. We have lots of old historical and vital records, but none leather-bound or particularly valuable.
There was no record in the catalog for this item at our library (although a nearby library does have it) - which means this item could have been weeded and discarded, sold as a fundraiser, or stolen by fiends any time in the last 100+ years.
Since we have no way to know, there's nothing we can do. I do occasionally hear about stolen library books being sold at auction (or worse, maps or color plates cut out of library books), but in this case I'm willing to give the benefit of the doubt. It is an interesting situation though. If anyone would like to purchase it and donate it to the library, please let me know.
