The process of information exchange is valuable in itself. It allows bulletin editors to learn about new developments, issues and concerns of colleagues working in the same field in other countries. Informal exchanges are very frequent, particularly concerning pharmacovigilance data, and on new drugs which are launched at nearly the same time throughout the world. The ISDB Newsletter also provides a forum for information exchange between bulletins. Electronic media are also useful, for example the English e-mail discussion list ‘E-drug’ [http://www.essentialdrugs.org/] (there are also essential drugs networks in French, Spanish, Russian and for India via the same web site), Healthnet [http://www.healthnet.org/] and INDICES [http://www.essentialdrugs.org/indices] and the network of editors of ISDB member bulletins (to find out about this, visit http://www.isdbweb.org).
