NIB was one of the earliest university-based research centers on the subject of biomedical informatics to be officially established in the country.

Starting 1996, NIB created a number of websites to provide health-related information. The center also published several online magazines, as well as bulletins and newsletters distributed by email lists. NIB also created a project of scientific electronic publishing, the e*pub Group, where several exclusively on-line publications were created under it, such as the On-Line Journal of Plastic and Reconstructive Surgery and the On-Line Journal of Dentistry and Oral Medicine.
