I re-post this to bring all changes in LIS into one platform. If you have any information about some other changes in LIS, please do post it as thread.

A) International Context
1) International Federation for Information and Documentation (FID) dissolved in 2002: FID was founded in 12 September 1895 in Brussels, Belgium, by bibliographers Henri LaFontaine (1854-1943) and Paul Otlet (1868-1944) as the “Institut International de Bibliographie” (IIB) or International Institute of Bibliography. It was popularly known as the Brussels Institute. It has gone through a number of changes in name that reflect changes of conceptualisation of the field in which it operates. In 1931 the IIB became the Institut International de Documentation (IID) or The International Institute for Documentation. In 1938 it became the Federation Internationale de Documentation (FID) or the International Federation for Documentation. In 1986 the word “information” was added to the name but the acronym is retained. Thus it become Fédération Internationale d'Information et de Documentation (FID) or the International Federation for Information and Documentation. FID was one of the world’s oldest and most influential international library organizations. It was maintaining its headquarters in The Hague, Netherlands after 1934. In 2002 FID dissolved. Over the years, FID was responsible for creating standards for microfiche reproduction; conducting research on the theoretical aspects of information; and promoting research on the impact of information, communications, and knowledge on national economies and society. One of the publications of FID was FID Communications.
