The list of country and federation codes used some obsolete data relating federations to the FIDE continent and zone structure, but it was the best I could do at the time. Sometimes it's better to release a nearly finished prototype, then fix the errors, than it is to attempt perfection on the first release. This was one of those times. Here is a list of errors I corrected for this second edition.
- Added missing data to several federations.
- Added zone 1.10.
- Updated most Asian zones, i.e. 3.x.
- Added zone 4.4.
The Fide.com page, Zone Presidents, was useful to verify the European zones like the relatively new zone 1.10 for small countries. My own page Zonals : Links (and Other References) was useful for the recent history of changes to zone numbering, e.g.
Starting cycle 22 (2004-2005), zone numbering changed from 3.1a to 3.1, from 3.1b to 3.2, from 3.2a to 3.3, from 3.2b to 3.6, and from 3.3 to 3.5; 3.4 unchanged.
FIDE pages for individual federations were useful to verify current zone numbering. I discovered two federations, both in zone 4.4, which are not on my current list.
I'll tackle this discrepancy another time.
