Information scientist
The term information scientist developed in the latter part of the twentieth century to describe an individual, usually with a relevant subject degree (such as one in CIS) or high level of subject knowledge, providing focused information to scientific and technical research staff in industry, a role quite distinct from and complementary to that of a librarian. Developments in end-user searching, together with some convergence between the roles of librarian and information scientist, have led to a diminution in its use in this context, and the term information officer or information professional are also now used.
