How does AOP affect the calculation of Impact Factors and Citation Counts?
If someone cites an AOP article, using the DOI form of citation noted above, then Thomson Reuters (ISI), which produces various citation databases and calculates Impact Factors, is able to match the citation to the final indexed version of the article. Thomson Reuters (ISI) uses several data elements, including the DOI, to link citations to the original articles. If someone cites an AOP article this citation can link to the final (citeable in Volume/Issue) form of the article. Citations using the DOI form, as well as the Volume/Issue form, can all be linked and can contribute to the Times Cited count for that article. Citations to either form will contribute to the Impact Factor calculation, as long as they note correctly the journal and the proper publication year for the article.
