Based on the database of Web of Science(SCI-E,SSCI,A&HCI),we collected 172 publications of eight doctorate-granting LIS schools and departments,including 329 authors and 502 person times.With methods of bibliometric and social network analysis,the total situation of authors and research cooperation,co-authorship networks and productive authors were explored based on these publications from the aspect of authors.Results showed that the number of totaled authors was relative less,with no more than one of per capita publications.The collaborative degree of authors is 2.92,and the collaborative rate of authors is 86.63%.Collaboration among authors increases over the study period.Most of these papers are completed by three or more authors' collaboration.The collaborative degree with foreign authors is about 33.14%.Collaboration with foreign authors increases over the study period.Most of the foreign authors are from countries of the United States and Great Britain.Based on co-authorship of at least two papers,we identify 20 consolidated research groups made up of 61 authors.The co-authorship networks have a low degree of clustering.The main sub-networks are made up of"supervisors and students"and authors in the same institution.Currently,no author has published more than 10 papers in eight doctorate-granting LIS schools and departments.Just a small part of authors publish more than 3 papers.
