According to Merlin on the Web: the British Museum Collection Database Goes Public on the CHArt conference site, the British Museum are putting their entire catalogue online. The evaluation will make fascinating reading and I hope can be made public – I'd like to know who uses it and why, does the variation in detail and 'quality' of records matter to them, how much of the collection is accessed, how many corrections or requests for more information are made, and how public comments work in practice.
