Brian Stephenson@bstephen2·Aug 4, 2020Interesting to see this database, which I had read about. In the UK a #chess study enthusiast called Richard Harman built up a collection of endgame studies on index cards, indexed by material and features. He was regularly consulted by judges for 'anticipations' of new studies.1Brian Stephenson@bstephen2·Aug 4, 2020Richard died in 1986 and his Harman Database is now in my house. I kept it up-to-date for a few years but it was superseded many years ago by Harold van der Heijden's electronic database.1Brian Stephenson@bstephen2·Aug 4, 2020Card indices of #ChessProblem s exist around the World. The White-Hume Collection was split up years ago but some of it still exists. The Albrecht Collection in Germany is now on computer database and kept by Udo Degener.
