I recently came across 2 card indices, and would like to know more about them. From the best I can tell, one would use them both at the same time, each with 2 suits of cards in 2 separate pockets. Any sources that talk about their history and use would be much appreciated.Thanks!

I recently downloaded the "CardSource Card Index System" from Trickshop.com. I have downloaded most of their card magic and have found all of it to be of very high quality.

I found that 2 indexes is rather cumbersome. I use 1 red Q5 index from 13 steps to mentalism. This is one of the best secret weapons I have.

I think Supreme made a book about the card index.It showed a few ways to make themand some routines

Supreme Magic also put out a set (2) of brown vinyl card indexes. I bought them maybe fifteen years ago and still have them somwhere. They were usable except that vinyl can sometimes be a little tacky in warm weather. They came with a couple of pages of ideas for effects of the "any card called for" type.

Unfortunately, T. A. Waters does not give an historical source in his, "Encyclopedia of Magic and Magicians". His entry only explains their use and references Max Andrew's "Sixteen Card Index Gems".

Barajista,

I might be mistaken but I believe that there is a substantial amount of info on the card index in Corinda's "13 Steps to Mentalism". (Maybe I'm thinking about Annemann's "Practical Mental Effects".)

There is also a booklet called "Charlie Miller on the Card Index",
that I can recommend.
