Bulletins
When Dave Sheppard retired in 2020 he kindly gave me permission to publish the contents of his website (originally named after his firm, "Dave Sheppard Associates", then called "MHAandMCA"). It is a treasure trove. I've not had time to prepare everything for publication but have put the main headings online: let me know if you would like a copy of anything listed.
The "Keeping up to date" bulletins ran from issue 1 in February 2003 to the final issue, issue 207, in April 2020.
