Birger Hjørland (born January 1, 1947, in Denmark) is a professor of knowledge organization at the Royal School of Library and Information Science (RSLIS) in Copenhagen.
Hjørland has emphasized in many papers that any work in library and information science cannot be "atheoretical", but should be based explicitly on some theoretical approach.
Its main premise is a set of analytical tools that can be applied in subsets or as a whole to in order to study the effects of different social, epistemological, and cultural fields on the theories of information science.
[6] In recent years, Hjørland has done research on Wikipedia as a part of establishing an information science-grounded kind of source criticism.
[7] As a part of the research, Hjørland has edited Wikipedia himself, making contributions to several articles related to information science.
