Changes

Editions 1-10 were A4 sheets produced on a hand-operated duplicator, the current A5 booklet format was adopted from issue 11. Since issue 11 the format has remained consistent, although increasing in size from 20 pages + covers to 72 pages in issue 208 (Winter 2019) . Sizes do vary according to other material to be posted, to save postage. Issues 209 and 210 (Spring and Summer 2020) were 64 and 56 pages in issue 209 respectively, the latter to allow inclusion of ''The Way Ahead'', a [[2020 coronavirus disease (Spring 2020COVID-19)pandemic|COVID-19]] themed supplement.
