Continuing with TMERs : One Step at a Time and finishing Carlsen TMER: Polishing the PGN, I split the large PGN file into separate files for each event and uploaded them to Magnus Carlsen's Tournament, Match, and Exhibition Record (2000-), TMER, 'Last updated 2013-07-15 (under construction)'.
The ZIP file contains 169 PGN files for individual events and a TXT index file suitable for loading into a database. For early events represented by a game or two -- where it isn't certain which games apply to which events -- I combined them into a YYX-MISC file
I know the split file is less useful to many people, but given the right tools it isn't difficult to recombine the small files into one large file. The small files make the project easier to maintain and provide a name to attach notes to individual events. Next step: Add the file names to the TMER.
