The service provides measures of popularity and influence of published papers and authors. It generates data recording how often a publication is cited by other scholars and how influential those citations are within the author's field. Data conform to the Standardized Usage Statistics Harvesting Initiative (SUSHI) protocol (ANSI/NISO Z39.93) for data about usage of electronic resources.
API methods support access to reports that track citations of a publication in journals, databases, and books. Returned data can be formatted according to the provider's proprietary COUNTER protocol or the SUSHI standard.
Understanding the usage of your publications used to be easy: if it's a book, count the sales. A magazine? Count the subscriptions. An article--count the circulation of the hosting publication. If you're a librarian, just look at how many times it was checked out. For impact, count citations. The digital universe requires new tools to measure these and the Scholarly IQ API is Scholarly's app for putting them right into your application. Scholarly IQ uses SUSHI to harvest COUNTER usage statistics.
