In addition, about 70 books had been published as of the beginning of 2000. Ursa publishes frequent press releases for newspapers, magazines, television, radio, etc. Photographs from Ursa's photo archive are rented quite often. Ursa has also developed several computer programs to explain astronomical phenomena. There is so much to observe that it is not possible for one person to effectively observe all kinds of phenomena.
All sections help to coordinate the work of amateurs, giving advice and collecting observations.
Sections also interact with each other and have cooperating activities. The most important form of cooperative activities is the Cygnus summer meeting. The newsletter Ursa Minor is a media where all sections report the results of their observations and news about current projects. It is published six times a year at the end of even-numbered months. Each section has its own column.
