If I could make a suggestion, why don't we have several threads, each dealing with a different book? This would allow a greater number of members to discuss their interests. In other words, possibly one thread for a book on cards, one on mentalism, one on stage magic, one on bizarre magick, one on magic theory, etc...
We don't need too many going at once, but it may be nice to have at least two or three per month to provide some variety. This way more than one interest is represented at a time.
Also, the idea of polling the members to choose the books sounds perfect. However, I personally would not restrict the selections by the age of the book (although most of the ones that I would love to discuss would be a number of years old.) The reason is that we may be excluding a number of people that simply do not own extremely old books.
And to answer your question Richard, I will help with moderating as much as I can. (I am out lecturing quite a bit over the next few months, but I will help when I am able.) Please let me know how I can assist.
Keep the change,
