Bother! and I've just this last Friday done the subject indexing for the GURPS chapter of the bibliography and could have answered this question in about 3 seconds!.
But glad you found it!
(have now (subject) indexed the MT, TNE, T4, GURPS, T20, HERO and T5 sections. Just CT and MgT to go now (but they're the big ones). Very tedious work but getting there. (These are planned as 'extras' to go with the author, title, date and publisher indexes.) (Yes, the indexes will pretty much double the 250 pages Andy already has).
And no, I've not heard from him for a bit of what the status of publication is. (The idea always was to get it 'out' and let the subject indexes be later additions as I thought they'd take me a year to do. Too much (dull) football on tv means I've got on faster than I expected! :-)
Have a great week one and all.
