Public Library of Science (PLoS) recently introduced article-level metrics.
The PLoS article-level metrics are a substantial value-add for authors, including a range of download statistics, citations and social bookmarking data, and more. As an author, I would love to see this kind of service!
It is interesting that a publisher with top-ranking journals on traditional metrics (impact factor) is also a publisher innovating in the area of metrics of far greater relevance, which say soon make impact factors irrelevant in the near future.
One service that I, as an author, would like to see for the future, is a means of combining statistics from institutional and disciplinary repositories with the publisher’s statistics. This is a development that could be pursed either by publishers or by repositories.
The data available from PLoS (from the PLoS website) includes:
Article usage statistics – HTML pageviews, PDF downloads and XML downloads
Citations from the scholarly literature – currently from PubMed Central, Scopus and CrossRef
Social bookmarks – currently from CiteULike and Connotea
Comments – left by readers of each article
Notes – left by readers of each article
Blog posts – aggregated from Postgenomic, Nature Blogs, and Bloglines
Ratings – left by readers of each article
