Item Can We Get Some Order Here? The Application of Principles of IT Project Management for Online Library Projects(Texas State University Libraries, 2012-01) Uzwyshyn, RaymondThis article overviews principles of IT project management for online library projects. It reviews project management methodologies, SWOT analysis, stakeholder documents, agile programming and project management methodologies for library IT and other large library projects reflecting on efficacy and necessity on these projects, especially in the case of large technology projects.Item Comparison of Association Between LC Subject Headings And Class Notations in Single- and Multiple-Heading Records(1987-10) Khosh-khui, Sam AbolghasemSubject headings and their corresponding class notations of 101,347 of the Library of Congress MARC records were analysed to determine variations in the association between Library of Congress Subject Headings (LCSHs) and Library of Congress Classification Notations (LCCNs) with respect to the variations in the number of subject headings per record. As the number of LCSHs per record increased, the association between LCSHs and LCCNs decreased. The probability of having identical LCCNs for identical LCSHs in single-heading records was found to be significantly higher than in multiple heading records. This implies that in recommending a class notation to a patron, distinction should be made between single- and multiple heading bibliographic records.Item Developing an Open Source Digital Scholarship Ecosystem(International Conference on Educational and Information Technology, 2020-02-11) Uzwyshyn, RaymondThis research presents elements necessary to develop a Digital Scholarship Research Ecosystem for a university, college or research institution. Software systems, hardware, human resources and timelines are outlined with brief theoretical overviews and a pragmatic focus on ‘open-source’ (freely available) software, best-inclass applications and global best practices. Major digital scholarly system components in a larger digital ecosystem are discussed: Online Institutional Collection Repositories (D-SPACE), Online Research Data Repositories (DATAVERSE), Identity Management Systems (ORCID), Electronic Thesis and Dissertation Management Systems (VIREO), Academic Journal Systems (OJS3), Digitization Labs, User Interface Software (OMEKA). System assessment, synergistic possibilities and future directions are reviewed. This research arises from a successful five-year phased implementation of such a digital ecosystem for Texas State University Libraries, a large US university research library system. This scholarly ecosystem is suitable for any university, college, research institution or academic research library interested in setting up or building on such an infrastructure and enabling faculty and graduate students with their scholarly research online.Item Effects of Variations in the Order of Subject Headings in Bibliographic Record on Association Between LCSH and LCC(1987-10) Khosh-khui, Sam AbolghasemLibrary of Congress Subject Headings (LCSHs) and their corresponding Library of Congress Class Notations (LCCNs) in 101,347 MARC records were analyzed to determine effects of variations in the order of subject headings in bibliographic records on association between subject headings and their corresponding class notations. The analysis revealed that LCSHs listed first had a significantly higher association with their corresponding LCCNs than the succeeding headings. The findings imply that in filing identical subject headings, it would be more logical to subarrange entries by order of subject headings in bibliographic records.Item Relationship Between LCSH and LCC Notations in Different Classes of LCC(1987-10) Khosh-khui, Sam AbolghasemAssociation between Library of Congress Subject Readings (LCSHs) and their corresponding Library of Congress Class Notations (LCCNs) was measured in term of probability of having the identical LCCN for all occurrences of a given LCSH in a database consisting of 101,347 MARC records. The measurements were controlled with regard to main classes of the Library of Congress classification (LCC). The analysis was repeated for all LCC main classes to determine if there are significant variations in association between LCSHs and their corresponding LCCNs in various classes of LCC. The degree of association between LCSHs and their corresponding LCCNs was found to be statistically significant among different classes of LCC. Class 'T' (Technology) had the strongest degree of association and Class 'A' (General Works) had the weakest level of association.Item Repetition of Information in OCLC MARC Formats: Implications for Library Automation Systems(1988-04) Khosh-khui, Sam AbolghasemAdvances in technology have made larger and yet less expensive computer memory available to libraries. A1so, the increased speed of processing has made access to any element of a huge data base possible in a fraction of a second. In spite of less cost for memory storage and high speed technology, there is always room for more efficiency in dealing with an ever increasing gigantic bibliographic data base. OCLC (Online Computer Library Center) is the oldest and largest bibliographic network in the United States. Many libraries use OCLC bibliographic records for their library automated systems. OCLC MARC (Machine-Readable Cataloging) formats, with few exceptions, follow the Library of Congress MARC formats for communication of bibliographic information in machine-readable form. However, examination of the structure of MARC formats and the contents for various types of materials, such as books, serials, etc., indicates that the data recorded in certain parts of the MARC structure are repeated. The adjustment in the OCLC display and/or print programs could result in reduction of average bibliographic record length and hence a saving in memory storage cost. The saving of memory, by avoiding duplication, could be very helpful to libraries with a limited storage capacity. It also could potentially decrease response time because the average length of bibliographic records would decrease. This paper compares information in the fixed field and variable fields and attempts to demonstrate some areas of OCLC MARC formats where more intelligent computer programs could be developed that would reduce the average time to input a record and reduce the size of the MARC records without any loss of information. It also points out certain areas where coded in formation is already used by the OCLC print program.
