Yesterday I finished my index for Wargames Illustrated, issues 1-259 (up to the takeover by Battlefront in 2009). These are the issues physically in my collection.
You can find the complete index, along with indices for Battlegames and Miniature Wargames with Battlegames here: http://snv-ttm.blogspot.be/p/wargames-magazine-database.html
I might still add some loose issues from other magazines to the database, but most of the work has been done. Of course, the description of specific articles can always be made better, so there will always be some further refinements.
