The table below lists Mailing Number, Number of Memberships, number of UK memberships vs Non UK (defined as place of residence), Number of Female members, number on Waiting List, number of UK fans on waiting list vs Non UK, Number of Zines in the mailing, page count for Largest Zine, Total Page count for the mailing. Numbers include post mailings - ie. zines not included in a mailing but sent out to members individually before the next quarterly mailing.

Note: This was a lot less straightforward to compile than I'd hoped due to inconsistencies in how pages were determined (US paper being larger meant allowance being made for the US quarto equivalent - but not always), zines not being listed and this not being noted until several mailings later, and the generally chaotic nature of Ken Cheslin's editorship.

Annual Totals, 1977/1978 Year ? ? ? * Everyone at the time believed there were 5 female members thanks to 'Joan Carr', of course. ** The fluctuation between 44 members and 45 from this point appears to be because the AE couldn't make up their mind about how to list Arthur Thomson and John Berry, joint editors of VERITAS. Others had issued jointly edited zines through OMPA before this, but Thomson & Berry were the first to do so with a shared membership. % This period should have seen the distribution of 9 mailings. It saw only 2. My history of OMPA is now available. Click on image for download page:
