Appendix C Publications Data NRC staff, with the assistance of staff at the George E. Brown, Jr., Library at the National Academies and using the SCOPUS database, tracked articles in the journals Corrosion and Corrosion Science for the past 22 years. In particular, the staff tracked the following data: ⢠Articles per year where the lead author was U.S.-basedâthat is, the authorâs home institution was in the United States. ⢠Articles per year that were drafted by an author based at a higher educa- tional facility compared with articles per year that were drafted by authors at government agencies, industry, and others. ⢠Number of academic institutions that had published articles compared with the number of government, industry, and others that published articles. The data tracked are presented in Figures C-1 through C-7. These data should be taken as a sampling that may signal a larger trend. 124

The overall decline in the percentage of articles written by U.S.-based lead authors. In 1985, 52 percent of all articles in Corrosion had a U.S.-based lead author.

There are generally fewer U.S.-authored articles in this publication than in Corrosion. The shares of articles with U.S. authors Figure C-2.eps are 16 percent in 1985 and 9 percent in 2007.

The data seem to show that while U.S.-authored articles as a share of all articles seems to decline over time, U.S.-academic-authored articles as a share of all articles seems to have declined much more slowly.

Data seem to indicate that while authors with Figure C-5.eps government and industry affiliations dominated until the mid-1990s, in more recent years, authors at academic organizations have been the larger source of articles.

The data seem to indicate a spike in overall U.S. authorship in the late 1980s and early 1990s, followed by a decline. While government/industry authorship seems to have declined, academic authorship seems to be holding steady.
