    24. 24. Strengths (contd) Facilitates ILL by making collections of other libraries accessible Beneficial for collection analysis  Download list of titles to Excel  Facilitates creation of collection development policies High standards for cataloguing Extensive search results  But might also be considered weakness if people do not check relevancy?
    25. 25. Weaknesses Some librarians consider such systems to be obstacle for acquiring information literacy skills  Relevancy of searches, ease of searching Serials often not included High standards for cataloguing but perhaps more flexibility needed  Encompass records from many sources  Allow for creation of more records Make better use of automation for updates
    26. 26. Suggestion Tiered approach for standards (Turner, 2009, 275)  Basic rules for all records with more detailed rules being “best practices”
