A basic analysis of sources, dates, authors for a Marine Biological Laboratory SAIL meeting - Wilmington, N.C. - May 14, 2009 Kathleen Heil, UMCES, Chesapeake Biological Laboratory, Solomons, MD
In these tough financial times when science is becoming more interdisciplinary and subfields are expanding as are number of titles in the sciences I wanted a way to evaluate material usage. Since most of our journals are now accessible on-line I had lost my major source of input on usage, which was re-shelving and observation.
Citation analysis has merits and limitations, but has many applications beyond collection development. Although I haven’t gotten further than the collection development access at this point. My future goal is to show institutional relatedness. (How broad or limited are our institutional connections)
CBL has always had very strong ties to the University of Maryland 1925 Founded under Dr. Truitt from Univ. of Md. 1930’s Start of summer programs 1941 Sponsored by the Md. Conservation Dept and became the chief component of the State Dept. of Research and Education 1961 Md. Legislature created the Natural Resources Institute as part of the University of Maryland ◦ Summer Classes began as Credit courses toward degrees 1973 Became part of a new Campus of the University of Maryland System - The Center for Environmental & Estuarine Studies (UMCEES) 1997 Became UMCES (University of Maryland Center for Environmental Science.
1976 Graduate students formally began work during the school year as part of their graduate school experience The first degrees were issued in : ◦ 1976 MS under the Dept of Botany University of Maryland College Park ◦ 1981 PhD Under the Dept of Microbiology University of Maryland College Park
Compare and contrast literature citations from MS & PhD theses/dissertations ◦ Identify citation patterns ◦ Formats of materials used ◦ Most frequently cited material ◦ Differences between subject areas
Use DRUM, the University of Maryland Dspace Open Access archive to pull UMCES-CBL theses/dissertations from the last 5 years. Copy and paste references into Word and then move them into Excel. Put each thesis/dissertation into a new tab Sort data into uniform format: author, year, title, source.
Sort by year Graph Hope to get to soon - ◦ Use find replace function to switch years to age

I reviewed a merged listing of publications After doing sort on material type There were 40 journal titles that had over 10 citations Range from 10 to 119 The highest used title was Environmental Science and technology
