ACS 

The ACS clearly sets the standard in the world of cricket stats and history but I think some of the books have been weak eg: Famous Cricketers (a few clunkers here though a 100 were published) Some of the Journal Articles were low on James quality(out of 100's). A recent series of short autobiographies seems interesting though I believe the Alun Watkins book was described as anodyne.
Incidentally I believe a tension has grown up between Cricketarchive and the ACS.(Last AGM) Oh and I am not a member but know several very well.)
