About the Map This map, which uses the five years of ILL data upon which this study is based, was developed by GIS Specialist James Whitacre in consultation with Steve Witt, who was a researcher in the study preceding the current study. The orange lines illustrate where our outgoing materials are going. The blue lines show where these lent materials were published. Most of the borrowing institutions are within the United States. While most of the borrowing institutions were within the Midwest region, many outgoing materials went to the coasts, especially the Northeast and Mid-Atlantic region, as well as the West Cost, especially California. Many outgoing materials also went to the Southern United States, especially Florida, North Carolina, and Texas. Furthermore, the map makes it possible to distinguish the proportion of outgoing publications by country rather than just by region. Outside of countries in Western Europe and North America, the countries with the highest proportion of outgoing publications were Russia, Japan, India, and China. Measuring and Sustaining the Impact of Area Studies Collections in a Research Library Tom Teper, Mara Thacker, Joe Lenkart, Esra Coskun University Library, University of Illinois at Urbana- Champaign Introduction This study examines the recent interlibrary lending history of developed area studies collections in order to evaluate the impact of resource sharing and cooperative collection development. By examining five years’ of a major research library’s resource sharing data for outgoing materials in Less Commonly Taught Languages (LCTL) and outgoing materials published with a foreign imprint, the authors will seek to draw conclusions about a cooperatively stewarded collection and make recommendations about the directions that research libraries should pursue in order to provide service at a regional and/or national level. Methodology 1.Used five years worth of the University of Illinois Urbana Champaign’s Interlibrary Loan data 2.Information that could be used to identify individual borrowers was redacted from spreadsheet. 3.The monthly files were consolidation into annual files for the years 2009 through The purposes of our analysis, the data was further processed to add an additional field to the original data set to show which world region an imprint was associated with. 5.The world regions were selected to align with the divisions used by the United States Department of Education in the Title VI applications. 6.Initial analysis of the results focused on materials from Africa and East Asia, and materials in the languages associated with those regions. Action Items/Impact Demonstrates that publication language is an inadequate measure of the value for area studies collections. Demonstrates that resource sharing is still beneficial, as lending these materials does benefit the broader scholarly community. Demonstrates the impact of these materials beyond the scholarly community, especially in local, state, and federal government offices. Demonstrates the value of strong public services programs (in discovery and access) in meeting local needs, as many local needs are fulfilled with items from afield. Further Work An examination of holdings juxtaposed with the publishing output of regions to see whether library holdings are reflective of world publishing trends Need for research libraries to aggressively begin defining areas of concentration and collaboration in order to more fully collect the breadth of scholarly output For those libraries and area specialist groups that are heavily engaged in cooperative collection development, an assessment of the efficacy of these programs would be useful Examination of corresponding local circulation data of materials lent to draw further conclusions about viability of cooperative collecting Interlibrary Loan Map
