Digitality and Research: What has Changed Christopher C. Brown Associate Professor Reference Librarian, Penrose Library Presentation given April 7, 2009 DMST 3010: Digital Noesis Prof. Frank Dance
Information Eras Orality Literacy Digitality
Changed: Mode of Access Users don’t want print journal content Books are tolerated in print, largely because electronic book technologies are not as advanced and accepted as electronic journal technologies
Online Serials have Grown Source: Osborne, Andrew D. Serial Publications: Their Place and Treatment in Libraries. Third ed. Chicago: American Library Association, 1980, p. 25.
E-Journal Growth at DU
The Information Access Anomaly: Books vs. Periodicals Book (average) Journal Article (average) Typical Length - full text (FT) 200 pages x 4001 = 80,000 words 15 pages x 4001 = 6,000 Surrogate Record (SR) 50-100 words (75 ave.) 300-500 words (400 ave.) SR to FT ratio 1 to 5333 1 to 15 1Ave. 400 pages per book (http://www.writersservices.com/wps/p_word_count.htm) Research methodology has changed. Starting point has changed. 1970 research: Books (card catalogs, book reviews) Journal articles (print indexes, print citation indexes)
Changed: Research Starting Point 1970 – Books accessed via card catalogs and book reviews 1970 – Journal articles access via print indexes 2009 – Books accessed via online catalogs, digital repositories, Google Books 2009 – Journal articles accessed via library subscriptions to publisher sites, aggregated journal content, reference linking from online indexes, and Google Scholar
Changed: User Expectations False sense that everything is online. While over 1,000,000 of the 2,300,000 Peak records contain online content, many of these are historic pre-20th century publications.
Changed: Non-Digital Formats Ignored Users take path of least resistance when doing research Users stop short of finding research if it is not conveniently online Users often overlook print or microfiche resources if it is not convenient for them.
