Roger Bland of the PAS will be speaking about the PAS and Treasure Act before a number of AIA chapters around the country. See http://finds.org.uk/news/stories/article/id/233
Given the audience, the lectures will touch not only successes of the system but gaps in the system as far as archaeologists are concerned. See http://www.archaeological.org/lectures/abstracts/5775
No system is perfect, but hopefully the AIA grandees will also pause to consider how the system in Britain and Wales compares with the systems (such as they are) in places like Bulgaria, Cyprus, Greece, and Italy, when it comes to encouraging members of the public to report their finds.
