Since this week's parashah mentions the hyrax, I've decided to make the chapter on hyraxes from my forthcoming Torah Encyclopedia of the Animal Kingdom available as a free download. Click on this link to download it (7.5 megabyte PDF).
Much of the information in this chapter is the same as in my book The Camel, The Hare And The Hyrax (with the addition of some small sections, and some amazing pictures that I found). However, it is organized very differently. When I wrote The Camel..., I presented the information yeshivah-style: A list of all the opinions that identified it as the hyrax, a list of the opinions that identified it as a llama, a rabbit, etc. But now that I have undergone academic training, the information is presented in a more meaningful way. The chapter explains how the various opinions arose, based on the context of the scholars.
I'm still tinkering with the page layout of the encyclopedia, so if you have any comments, please let me know; I think that the title bar for each chapter (where it mentions the animal's name in English and Hebrew) needs improving, but I'm not sure how.
On another note, I will be visiting Canada (Toronto and Montreal) for 10 days over Shavuos; I will post my speaking schedule once it is finalized. I also have a free Shabbos in New York on August 2-3, if anyone wants to arrange a scholar-in-residence program; please write to me if you are interested.
