What is a Master Record?

The MOBIUS union catalog record display is similar to those in the local catalogs. Author, title, publication information, etc., appear toward the top of the display.

Description, subject headings, control numbers, etc. appear toward the bottom of the display.

In between these two sections, the holdings for MOBIUS’s local systems are displayed.

In a local Sierra catalog, the primary display is taken from a bibliographic record, while the holdings display is taken from “attached” item or holdings records. In INN-Reach, both the primary and holdings display are taken from bibliographic records. The bib record that appears in the primary display is called the Master Record; the records that appear in the holdings line are called Institutional Records.
