Chapter three is one of our most comprehensive documents, and as such is too large for a single page.

Overview

Overview The first phase of MARS 2.0 Authority Control comprises a wide variety of routines that update and correct individual subfields and contiguous pairs of subfields. These corrections are based on a number of subfield update tables maintained by MARS 2.0 authorities librarians.

Authority Cleanup cleans up headings to facilitate matching on national-level authority records during the matching process. MARS 2.0 Authority Cleanup subfield correction routines include:

  • Updating obsolete forms of subdivisions to the current form
  • Correcting common typographical errors
  • Expanding abbreviations in subject subfields to their fuller form
  • Converting common direct geographic subdivisions to their indirect form
  • Deleting subject subdivisions which have been canceled or discontinued
  • Correcting spacing, capitalization, and punctuation
