摘要：Scholarly communication through Open Access (OA) journals has become a global phenomenon. This article reports on a study that measures the value of OA journals based on citation counts (ISI’s Journal Impact Factor). It compares three highly ranked commercial electronic journals to five OA electronic journals. The non-OA journals are MIS Quarterly, Journal of American Medication Informatics Association, and Annual Review of Information Science and Technology; the five OA journals are Ariadne, D-Lib Magazine, First Monday, Information Research, and Information Technology and Disabilities. The criteria are established by ten major databases: Thompson’s ISI, American Psychological Association’s PsycInfo, Latin American and Canadian Health Science’s LILCS, National Medical Library’s MEDLINE, Scientific Electronic Library’s SciELO, The IOWA Guide, CSA’s LISA, EBSCO’s LISTA, H.W. Wilson’s Library Literature and Information Science, and R.R. Bowker’s Ulrich International Periodical Directory. These basic criteria are categorized under 11 broad issues: availability, authority and review policy, scope and coverage, exhaustiveness of articles, page format, availability of hyperlinks, currency, updating policy, search facility, and other miscellaneous issues. Ten years’ growth of Library and Information Science (LIS) OA journals has been measured by counting articles manually. During the last ten years the highest number of articles was published by First Monday, followed by D-Lib Magazine and Ariadne; the average number of articles per issue reported in Ariadne ranks first.
