Those Joy of Cooking books really are monsters to index - they
have 12 times more recipes than the average cookbook. We have
just added our second one, the 2006
75th Anniversary edition. At almost 3,000 recipes it took
months to index - we kept having to give the indexer (Martha)
breaks on other gentler books so she didn't crash and burn.
We have one more edition, the 1997 6th edition to finish - then
that will be more than 9,000 recipes on EYB just from Joy of
Cooking.
