Call# conversion project from Dewey to LOC: fall 2020 - Summer 202? 

  • Phase I = Automatic generation of LOC numbers (into a temporary field) through an extensive MARCEdit and OCLC call number  build - finished 1/25/21
  • Phase II = Go through remaining records (that didn't get an automatic assigned LOC call#) and manually create an LOC call#. As the dates become factors of obsolecense the items will become marked as candidates for weeding/de-selection.
  • Phase III = Adjustments from quality control through virtual shifting
  • Phase IV = Become an official LOC library through an orchestrated transfer of fields, labels, and shelf placement.



LOC has become the defacto standard in academic libraries, and as Chatham continues to "expand" and our materials become more visible via resource sharing, our presense as a bonafide academic leader will remain intact. These records that didn't get an automatic LOC assignment through the phase I process represent about 1/4 of the total circulating collection, and were bypassed in a recent inclusive call number re-build of the catalog. Aside from very recent records (post-2000) and obscure gems, these assigned records have very little or no acknowledgment of viabilty in the bibliographic universe, and thus are prime candidates for de-selection (weeding).finished 1/18/22


Now that every item has an assigned LC call#, go through the ENTIRE collection and do a quality control of all records, adding the publication year as the suffix of the LC call#.
