In the various bibliographic databases with which we work, there are certain symbols used to represent the University of Illinois Library. These symbols, codes, or abbreviations must be used consistently and correctly.
This is the OCLC symbol assigned to the University of Illinois at Urbana-Champaign. It should always and only be used in the 040 field.
This is the MARC21 code (as opposed to symbol) for organizations within the University of Illinois. A hyphen and subsequent letter indicate the specific part of the University of Illinois. “ -R” indicates the Rare Book and Manuscript Library. Therefore, all local 500 notes and other fields in MARC bib records which end with the institution-specific code must, in our case, end with ≠5 IU-R. The IU code should also be used within notes to refer to this library; e.g., “IU copy has....” (not “UIU copy” or “UIUC copy”).
This is the organization code used to represent this library in ESTC. The “n” signifies North America. For our purposes, we use this code when annotating an ESTC record, under Library. As above regarding 500 notes, this code should be used within the annotation; e.g., “nIU copy has....” or “nIU copy IUQ01788 lacks....” (not “UIU copy”) .
