I don't know if this solution will work for others, but I find it useful. Whenever I enter my cookbooks, I bookmark them either Indexed or Not Indexed. I can then bring up my Not Indexed list and it has the book covers and the information about Index Soon or Index Requested, etc. Whenever a cookbook is indexed, I find great delight in changing the Not Indexed bookmark to Indexed!
Every once in a while, I do a search checking "show indexed books only" while using my bookmark Not Indexed. Any book that has recently been indexed without me noticing it shows up and I change its status.
I also mark my indexed books with a blue round sticker and my "not indexed" with a yellow one. This lets me know visually which books are not searched in case I want to check the book itself.
I must say, I love EYB! Only thing, since joining here and then also finding Chowhounds, my cookbook collection has grown considerably. I'm also using cookbooks that wouldn't have before because I wouldn't have thought to look in them for the recipe I found using EYB.
