Unless you own the 1997 four part version of the Blue Volume I, you are aware of Scott's interesting take on alphabetizing. To this day, I have trouble remembering where some countries fall in the sequence, or rather out of sequence. Fortunately, fellow collector Keith Arbtin has compiled a country-by-country index, not only for Volume I, but for the first three volumes which cover 1840-1956. Many thanks to Keith for his work and for giving me permission to make it available to others. I know every Blue collector will find it useful.
If you would like a PDF file of Keith's index, send a comment on this post (which I won't publish) with your email address and I will forward a copy to you.
UPDATE: Al L, if you are reading this, please send me your email address in a comment. (I won't publish the comment.)
