EPA REPORT - DRAFT
January 5, 2006

This is a bibliometric analysis of a collection of 388 EPA-EDC papers. For this report, 283 papers were reviewed. The data breakdown from the 388 citations provided by EPA is as follows:

  • 283 successful citation results
  • 67 records omitted for the following conditions:
    • 12 duplicates
    • 20 book records. Thomson indexes primarily journals.
    • 4 journals not indexed by Thomson
    • 21 records where there was no article for the author, journal, or title listed by EPA
    • 10 records with a status of “In press” or “In review”. No published citation found

The remaining citations will be double checked for inclusion in the final report.

The analysis was completed using the Thomson Essential Science Indicators (ESI) and Journal Citation Report (JCR) as benchmarks. The following is a summary of the EPA-EDC papers compared to ESI and JCR.
