Maps on the basis of the Arts & Humanities Citation Index:
the journals Leonardo and Art Journal¸ and “Digital Humanities” as a topic

Abstract: The possibilities of using the Arts & Humanities Citation Index
(A&HCI) for journal mapping have not been sufficiently recognized because of
the absence of a Journal Citations Report (JCR) for this database. However,
any document set contained in the ISI domain can be used for bibliographic
coupling and co-citation analysis. Furthermore, we explore the possibilities
and limitations of the construction of a quasi-JCR for the A&HCI (2008). At
http://www.leydesdorff.net/ah08/cited/index.htm and
http://www.leydesdorff.net/ah08/citing/index.htm cosine-normalized citation
matrices for all 1,157 source journals to the A&HCI are brought online in
Pajek format. 

We compare the maps of two art journals -- Leonardo and Art Journal -- in
terms of how they inform us about the relevant citation environments, both
cited and citing. Using animations, the presence and reproduction of
structure can be examined. The journals share a common knowledge base in
their reference patterns, but their cultural impact is much wider than the
limited domain of the A&HCI. “Digital humanities” is additionally analyzed
as a topic. The topic seems to function as an intellectual focus more than
the journals.
