  1. Citation Analysis of Theses/Dissertations 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

  2. Introduction: 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.

  3. 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)

  4. Background: • 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 andbecame 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 partof a new Campus of the University of Maryland System - TheCenter for Environmental & Estuarine Studies (UMCEES) • 1997 Became UMCES (University of MarylandCenter for Environmental Science.

  5. Background/History (continued) • 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

  6. Objective: • 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

  7. Methodology: • Use DRUM, the University of Maryland Dspace Open Access archive to pull UMCES-CBL theses/dissertations from the last 5 years. • http://www.lib.umd.edu/drum • 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.

  8. Find usage by year • Sort by year • Graph • Hope to get to soon - • Use find replace function to switch years to age

  9. Identify Materials Cited A / V Audio tape / Video B Monograph C Conference Paper D/TH Dissertation / Thesis Go Government document/web site Gr Grey Literature J Journal M Magazine N Newspaper P Personal Communication S Software T Technical report W Web site/ web page

  10. Journal usage trends: Title dispersion Proportion of journals cited Most cited Journals

  11. Most Heavily Cited Journals • 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

  12. Top 5 cited journals

  13. MS These Sources by type

  14. MS Theses Top 20 Journals
