The database provides some measure of the academic impact of the papers indexed in it, and may increase their impact by making them more visible and providing them with a quality label. Some anecdotal evidence suggests that appearing in this database can double the number of citations received by a given paper.

Within the scientific community, journal impact factors continue to play a large but controversial role in determining the kudos attached to a scientist's published research record.

Listings were based on published selection criteria and are an indicator of journal quality and impact.

ISI Highly Cited

"ISI Highly Cited" is a database of "highly cited researchers"—scientific researchers whose publications are most often cited in

s over the past decade, published by the Institute for Scientific Information. Inclusion in this list is taken as a measure of the esteem of these academics and is used, for example, by the

. It was founded under ISI and as of 2018 continues under the same name at Clarivate. The methodology for inclusion is to consider papers in the upper first percentile based on citation countsWelcome to Highly Cited Researchers
retrieved July 6, 2014 of all articles indexed in the Scientific Citation Databases and published in a single, fixed year. Papers in the upper first percentile with respect to their year of publication are called highly cited papers. Each paper in the data is assigned to one or more of 21 categories, based on the ISI classification of the journal in which the article was published. The Highly Cited Researchers list is compiled by selecting, in every field, those researchers with the highest number of highly cited papers in a 10-year, rolling time period. The number of highly cited researchers varies from field to field and is determined accordingly to the total number of researchers contributing to the single field. The categories are as follows: The publication list and biographical details supplied by the researchers are freely available online, although general access to the ISI citation database is by subscription.
