It's shofar season, and so for those who aren't aware of it, I am posting my annual reminder that you can freely download my illustrated monograph, "Exotic Shofars: Halachic Considerations," at this link: http://www.zootorah.com/essays/ExoticShofars.pdf. This is the third edition, complete with discussion of jackalopes as well as the biggest shofars in the world! Please feel free to circulate this monograph widely.
For those readers living in Israel: I have a presentation on this topic, for which I bring along my huge collection of shofars and related artifacts for a unique hands-on experience. If you are involved with a shul/ yeshivah and are interested in arranging to have me come and present it, please write to me at email@example.com.
