Hi Gamcgill,
I feel your pain. I have a huge number of cookbooks, both digital and all over the house and EYB has actually been a bit of an enabler as I now have the excuse that I will pay attention to them.
When I first joined, many of my books weren't indexed, but I quickly found that EYB really upped my use of the books that were indexed. And actually got a few more into the act, since they might be shelved nearby or come up on a search. I have books spanning back over 40 years, and am always pleasantly surprised when older volumes are indexed. I love used books stores, but what is not in print is not likely to get a greater number of users.
When I don't have the recipe I want in one of my indexed books, and can look over the unindexed titles and think about whether one of them might have the recipe I need. So even unindexed, EYB keeps my books in front of me.
Over the years, the balance has gone to more than half indexed. I think a bit harder about buying a book that isn't indexed, and I don't often buy unintentional duplicates anymore
Anyway, I hope you don't give up on EYB. I am not an indexer, so I cherish those members that are. In fact, there is a thread on underated cookbooks and one indexer was so enamored of one of my suggestions that she indexed it (thanks Vanessa). So if you have a couple of great ones that you think are underated, please post to that thread and let the rest of us in on the secret
