I read about this this morning
http://crowdsourced.micropasts.org/
http://www.theguardian.com/science/2014/aug/18/volunteers-british-museum-crowdsourcing-archeology
which gives volunteers a chance to look at old handwritten records of bronze age objects and transcribe them into a digital form. hmmm which then goes onto the Portable Antiquities database for some reason (less appealing to me that one should want to be assisting with that). It's been going since April but I don't remember it being mentioned here before, maybe it has.
