I released a new pgn collection called GrandM.pgn. It is a collection of human v human games for the years 1891 thru 1930.
It joins my other Grand pgn collections, N thru R. This new collection contains 20K games. They are long time control, over the board games between the top players of those years. No simul, no exhibition, and no correspondence games.
