The Amiga Format Special Editions were produced outside of the normal monthly publishing cycle and covered software guides, hardware guides, beginners' guides, annuals and other related items of interest. One item of note is that the issue that is marked "Issue 11" is actually more than likely in fact "Issue 10". There were two other "Extra Special" editions which were released as part of A1200 bundles and you could not buy them unless you bought the A1200 as part of that bundle. Those bundles being the "Desktop Dynamite" and "Comic Relief" packs.
NB: Please don't tell me about the use of apostrophe's on this page. All titles appear as printed in the respective Special Edition.
