  The structural properties of the network generated by the editorial
activities of the members of the boards of "Information Science & Library
Science" journals are explored through network analysis techniques. The crossed
presence of scholars on editorial boards, the phenomenon called interlocking
editorship, is considered a proxy of the similarity of editorial policies. The
evidences support the idea that this group of journals is better described as a
set of only relatively connected subfields. In particular two main subfield are
identified, consisting of research oriented journals devoted respectively to
LIS and MIS. The links between these two subsets are weak. Around these two
subsets there are a lot of (relatively) isolated professional journals or
journals characterized more by their subject-matter content than by their focus
on information flows. It is possible to suggest that this configuration of the
network may be the consequence of the youthfulness of Information Science &
Library Science, which has not permitted yet to reach a general consensus
through scholars on research aims, methods and instruments.
