Some time back, my wife and I published our medieval cookbook, How to Milk an Almond, Stuff an Egg, and Armor a Turnip. In addition to making it available as a paperback on Amazon, I also put a pdf of it up on my web page for anyone who wanted to download.
It recently occurred to me that it would get much more visibility on Amazon, and that some people would find a kindle more convenient than a pdf. I put the question to people on Facebook, and quite a lot of them said they would like it as a kindle.
So I converted my Word document to a kindle, using Calibre, a free conversion program. It's a nice program, and their technical support is fast and helpful. Despite that I ran into a lot of different problems, with the result that the conversion took something like ten to twenty hours, about ten times as long as I had expected. But it's now done and up on Amazon, and has sold thirteen copies in the last two days.
For those not familiar with it, the book consists of all of the cooking material from the Miscellany that Elizabeth and I have self-published for a very long time. It contains over three hundred medieval and renaissance recipes, in each case with the original (or a translation) and our worked out version. In addition there are articles on topics related to period cooking. I assume that most but not all of our customers will be fellow SCA members.
