Informing science is a transdiscipline that was established to promote the study of informing processes across a diverse set of academic disciplines, including management information systems, education, business, instructional technology, computer science, communications, psychology, philosophy, library science, information science and many others. Its principal unit of analysis is the informing system, a collection of informers, clients and channels that has been designed or has evolved to serve a particular informing need. The organization created to advance the informing science transdiscipline is the Informing Science Institute (ISI), whose founder, Eli Cohen, proposed the need for field in his article "Reconceptualizing Information Systems as a Field of the Transdiscipline Informing Science: From Ugly Duckling to Swan" (Cohen, 1999). The ISI presently host an annual conference (Informing Science & Information Technology Education (InSITE)), publishes seven academic journals, and—through its Informing Science Press--has published for dozens of books. Both its journals and books are open access at no cost online, as well as being available for purchase in print form.
