Abstract
The degree of interdiseiplinarity observed in the analysis of a research literature can depend on the analytical approach Subject assignments of highly cited journals and those frequently publishing topic-relevant articles are compared with data from a recent survey of neural networks researchers. Publication subject patterns parallel the survey results-concentrating heavily in the physical sciences and engineering-while the biological and psychological literature is more visible in citation patterns This finding may reflect both discipline-specific differences in size and publishing patterns and cross-boundary problems in the perceived usefulness of and access to published information.
