Julian Evan-Hart sort-of responds to my comments on his remarks about the finding of the Crosby Garrett helmet through a longer post on the Rally UK forum. For the enthusiast.
In the meanwhile somebody has pointed out to me that despite his somewhat instrumental approach to the PAS [apparently recommending liaison with "museums" more frequently - seemingly because they can help out with finding unprotected land to search on and may help conserve your finds], the PAS in its conservation notes cites as one of three recommended books on "conservation" Mr Evan-Hart's book: Beginner's Guide to Metal Detecting by Julian Evan-Hart & Dave Stuckey, Greenlight Publishing 2004. £9.95
You can find a summary of it here. Interesting reading, especially on "researching sites" - finding sites with lots of artefacts to collect that is.
