Who is Linked? A Comparison of Most- Linked and Least-Linked Academic Medical Library Web Sites The University of Texas Southwestern Medical Center Library Dallas, Texas
Agenda and Staff Involved zPurpose zMethodology zResults zMeaning zQuestions z Karen R. Harker, BA z Judi Hill z Sally Harvey, MLS, AHIP
What is …? Who are …? zThe Problem: y130+ links to UT Southwestern Medical Library y4,000+ links to Yale University Medical Library zThe Question: yWhat makes a site more likely to be linked? zThe Subjects: yAcademic Medical Libraries (AMLs) for schools listed in the AAMC directory. yOf 125 libraries, only 91 were able to be fully studied.
Who needs to know and why? zWho? yWebmasters yWeb page developers yOutreach librarians zWhy? yTo improve a sites visibility and prominence in the Web environment
What are the factors examined? zExternal Factors zInstitutional Ranking (US News and World Report) zLink to the Librarys page from the institutions home page zParticipation in IAIMS (Integrated Advanced Information Management Systems) zLibrary budget zSize of Librarys collection zPublic or Private institution z Internal Factors z Total number of links on all pages of the Librarys site z Number of links to sites external to the institution z Number of files in the site z Ratio of graphics to total number of internal links z Ratio of dead links to total number of links
How did we do it? zThree Phases yPhase I xSearch the number of links to each librarys site yPhase II xDownload the links from each librarys site yPhase III xCategorizing data generated from Phases I and II
How did we determine the number of links TO a site? zNumber of links TO a site ywww.InfoSeek.com ySearch engine yAble to search link:(url), which brings back a list of all those files which have a link to that URL yExcluded files from sites internal to the institution or library using -url:(url) z Number of links AT a site z LinkBot yFor Web-site maintenance which can generate a list of all links in all files at a site: library/*.*
How did we categorize external factors? zData on institutional factors were gathered from US News & World Report, AAMC Directory and the institutions Web sites. zData on library factors were gathered using the Annual Statistics of Medical School Libraries in the United States & Canada, 19th ed.
What did we find out? zNot all libraries receive the same amount of attention yAverage number of links to a site: 267 yMost were between 20 and 1000 yActual range was from 0 to 4700 yUT Southwestern Medical Library: 134
What does it look like?
Who are the most-linked and least-linked AML sites? zMost-Linked Sites zInstitutionLinks zYale University4700 zUniversity of Utah2404 zColumbia University2220 zWashington University1700 zVanderbilt1390 zUniversity of Washington1227 zLoyola University1220 zUniversity of Colorado1140 zUniversity of Missouri- Columbia 860 zUniversity of California, San Francisco 757 zJohns Hopkins University 738 zUniversity of Arizona 635 zMedical College of Georgia 630 zLeast-Linked Sites zInstitutionLinks zCWRU6 zMt.

What about external factors? zDifferences in the average number of links TO a site: yExternal Factors which were statistically significant: xBeing an institution in US News & World Report Top 25 Medical Schools xBeing a private institution However, 18 of the Top 25 Medical Schools are private xBeing a participant in IAIMS
What are the average number of links to each site concerning external factors?
What does this mean? ySuccess breeds success - Derek de Solla Price
What affects the probability of being in the top 25% most-linked sites? zExternal Factors: yUSNWR Top 25 Medical School yHaving a link to the site from the institutions home page zInternal Factors yTotal number of links AT a site yNumber of external links at a site
Points to remember zSuccess Breeds Success zSize Does Matter
Where do we go from here? zAnalysis of the links at these sites yWhich are the most linked-to sites by AMLs? yCan these links map the field of biomedicine? yWhat kind of information do these sites provide? zAnalysis of linking behavior yWhy does a Web developer link to a site? yWhy does a Web developer NOT link to a site?
Where do you go for more information? zHandouts of this session are available. zData and worksheets are available at:
