USING SCOPUS TO STUDY CITING BEHAVIOR FOR COLLECTION DEVELOPMENT A focus on Psychology Research at the University of Houston Irene Ke, MLS, MS Psychology & Social Work Librarian University of Houston [email protected] Psychology Research at UH A university in transition: Tier One initiative Psychology publication trend (University of Houston) Data source: SCOPUS Project Goal: Gather evidence for collection decisions Objectives: To learn How psychology researchers use information Whether the library collection meets campus research needs Essential questions How psychology researchers use information What journals were cited and how often? Time range (age) of sources cited (Do old materials matter?) Types of materials cited (Do books matter?) Whether the library collection meets campus research needs Does the library subscribe to the journals that researchers cited? Do researchers use the journals provided by the library? Methodology Data Collection: • Citation data: SCOPUS Strengths Limitations • Usage data: COUNTER, Serials Solutions (Focus on journals only) Download times Papers included in the study: • Published by a UH researcher between 2000 to 2013 • Papers were classified to “psychology” as a subject in SCOPUS Preliminary Finding I Time range (age) of sources cited (Do old materials matter?): “The year the cited source was published” minus “the year the citing paper was published” The peak time of an article being cited is between 1 to 8 years after its publication. 5 years Times of getting cited 300 2013 250 2012 200 2007 150 100 2006 50 2001 0 2000 0 5 10 15 20 25 30 35 40 45 -50 “The year the cited source was published” minus “the year the citing paper was published” Note: all source types are included in this analysis. It covers 6 years’ data: 2000, 2001, 2006, 2007, 2012, 2013 Preliminary Finding II How do campus researchers cite journals? A wide range of journals were cited: 543 journal titles were cited from 2002 to 2013 Only a small portion of journals get cited often: 33 titles were cited more than 100 times (about 6% of all cited journals) 368 titles were cited equal to or less than 20 times (about 68% of all cited journals) Most frequently cited journal: Journal of Applied Psychology (567 times) How do campus researchers cite journals? Titles cited more than 100 times. n= 33, “6% of total” Titles cited between 20 to 100 times. n=142 “26% of total” Titles cited less than or equal to 20 times. n = 368 “68% of total “ N= 543 Preliminary Finding III Do we subscribe to the journals that got cited? The library has a great coverage of the journals that were cited often: Journals were cited≥ 21 times Journals were cited ≥ 100 times Number of titles 175 33 Number of titles that Library subscribes to (full access) 161 33 % 92% 100% 10 1000 0 0 Number of times a title was cited in 2012 60 50 30 20 N=69 titles Journal of Applied psychology Vision research Clinical psychology review Journal of Management Brain Research American Journal of Speech-… Psychological Medicine Journal of International Business… Counseling Psychologist Human Resource Development… MIS Quarterly Management… Journal of Social Issues Violence & Victims Journal of personality disorders Journal of the Academy of… Organizational Dynamics World Journal of Surgery Journal of Abnormal and Social… Journal of Abnormal and Social… World Journal of Surgery Organizational Dynamics Journal of the Academy of… Journal of personality disorders Violence & Victims Journal of Social Issues MIS Quarterly Management… Human Resource Development… Counseling Psychologist Journal of International… Psychological Medicine American Journal of Speech-… Brain Research Journal of Management Clinical psychology review Vision research Journal of Applied psychology Preliminary Finding IV Does citation data aligns with usage (download) data? Citation (from Scopus) and usage data (from 360 Counter, Serials Solutions) comparison Number of times a title was downloaded in 2012 7000 6000 40 5000 4000 3000 2000 Preliminary thoughts What are the implications? For collection development Decisions on old materials Build the “core” Multidisciplinary approach Citation data only tells a part of the story, other types of data are needed For outreach Data proves our support to campus research (no apology anymore!) Data helps us to communicate with faculty members Work still in progress Type of materials cited Subject areas cited Questions? [email protected]
