Abstract

Walters and Wilder describe the literature of later-life migration, a multi-disciplinary topic, and evaluate its bibliographic coverage in seven disciplinary and five multi-disciplinary databases. Multiple database searches and reviews of the references of found items discovered over 500 papers published between January 1990 and December 2000. These were then read to determine if late-life migration was their central focus, and to select those which presented noteworthy findings, innovative approaches, or were covering topics unseen elsewhere, and also were understandable to a broad readership, and generally available. One hundred and fifty five journal articles met these criteria and are the focus of the study. The core journals of sociology, economics, and demography are not major contributors, but three gerontology journals are in the top five. The top two journals have broad coverage, but the others tend to concentrate on one of five themes. The top five journals account for 40 % of papers and the top twelve 70%. Of nine papers cited 30 or more times seven appeared in the top 12 contributing journals. The median article in the study was indexed by six of the twelve databases, and 12% were indexed by more than 7 databases. The correlation between citation and number of databases indexing a paper is very low. Social Sciences Citation Index will 73% coverage. Typical overlap in the 12 databases is about 45%.
