As far as we know no documentary exists that only treats the scientific research on crop circles. But to some extent most of these films show some of the research results as a part of the overall phenomenon.  Under Films at our web page, you’ll find a list of all the films that can be ordered on the Internet. We highly recommend seeing some of these films in order to fully understand the complexity of this fascinating mystery.

During the last few years many high quality and well illustrated books about crop circles have been published, each with its own particular angle to the phenomenon.  Some of them aim to give an overall presentation, while others focus on particular aspects like interpretation of the symbols, the mathematic aspect, holy geometry etc. Take a look at the list under Literature where you’ll also find the information you need to order.
