Zonal Qualifiers C01-C12 : Archive.org

Continuing with my previous post, Zonal Qualifiers C01-C16 : Archive.org, I noted the first steps for documenting the interzonal qualification process in C01-C12:-

I downloaded the three [GMG] pages from Archive.org and combined the ten different regional tables into a single table. I then split that table into cycles covering C01 through C16.

The tables for each cycle contain data about individual players plus info about the qualification process. For example, the data on the 20 players in the first Interzonal is shown here:-

C01 IZ Qualifiers

This should match my corresponding page on the 1948 Saltsjobaden Interzonal Tournament. Info about the qualification process for that same cycle is collected here:-

• 'Hilversum Zonal 1947 gathered the champions of the various European FIDE member nations together. O'Kelly de Galway of Belgium came 1st, but must have declined to play at Saltsjobaden. Trifunovic and Pachman shared second. Szabo came in a tie for fifth. Pirc, Gligoric and Tartakover were not invited to Hilversum, but were nominated by ballot by the FIDE directors to play in the Interzonal.'
• 'Isaac Kashdan came in second at the U.S. ch. of 1946. Reshevsky the winner was seeded into the 1948 World ch. at The Hague/Moscow, and Kashdan qualified to play at Saltsjobaden IZ 1948. Arnold Denker was selected by FIDE ballot, but apparently both Kashdan and Denker declined to play. Israel Horowitz seems to have been offered a place as well as a replacement, but must have declined as well.'
• 'Najdorf and Stahlberg shared first and Erich Eliskases came third in a strong tournament at Mar Del Plata in 1947. Eliskases must have declined to play.'
• 'All Soviet players were selected based on their results in ballots submitted by the FIDE directors. Boleslavsky came second at the 15th USSR ch. 1947, and Bondarevsky shared 3rd.'

This complements my corresponding page on the Zonals 1948-1951 (C01). In the 'C01-C16 : Archive.org' post, I also noted:-

There is some overlap in cycles C13-C16. I'll decide how to handle that when I come back to the subject.

For example, the first of my pages on those cycles is Zonal Qualifiers 1984-1987 (C13). Although I haven't decided how to handle the 'overlap', the C13 page shows the sort of thing I'm aiming at for C01-C12.
