I keep an eye out for anything interesting relating to my own research, and have realised that sellers and dealers on ebay have done us researchers a service - essentially digitising a whole load of archives that are unavailable publicly. So this site will hopefully help to collate a small fraction of them for future use.
I hope it will also mitigate against that impression researchers sometimes get when they've 'finished' looking through an archive at a record office or local studies library, and think that they've seen everything relating to a particular place or topic. One look at Ebay suggests that there's a huge load of unseen material out there in private hands.
