Using three-year moving averages of the complete Journal Citation Reports 1994-2016 of the Science Citation Index and the Social Sciences Citation Index (combined), we analyze links between citing and cited journals in terms of (1) whether discontinuities among the networks of consecutive years have occurred; (2) are these discontinuities relatively isolated or networked? (3) Can these disconti...

queries against a database of stored, indexed documents. However, many of these search engines have proved ineffective for searching scholarly publications accurately. Researchers have developed autonomous citation indexing agents, such as CiteSeer,4 to search computer-science-related literature online. These agents extract citation information from the literature and store it in a database. Ci...

An Impact Factor is one measure of the relative importance of a journal, individual article or scientist to science and social science literature and research. Each index or database used to create an impact factor uses a different methodology and produces slightly different results, revealing the importance of using several sources to judge the true impact of a journal's or scientist’s work.

Aggregated journal-journal citation networks based on the Journal Citation Reports 2004 of the Science Citation Index (5968 journals) and the Social Science Citation Index (1712 journals) are made accessible from the perspective of any of these journals. A vectorspace model is used for normalization, and the results are brought online at http://www.leydesdorff.net/jcr04 as input-files for the v...

Journal self-citations strongly affect journal evaluation indicators (such as impact factors) at the mesoand micro-levels, and therefore they are often increased artificially to inflate the evaluation indicators in journal evaluation systems. This coercive self-citation is a form of scientific misconduct that severely undermines the objective authenticity of these indicators. In this study, we ...
