MARC 21 Format for Bibliographic Data: 565: Case File Characteristics Note (Network Development and MARC Standards Office, Library of Congress)

Information about the content and characteristics of case files and/or the number of cases or variables making up a case file or a database.

Case files are interpreted broadly as records that contain standard categories of information about a defined population. Files may be composed of individual documents, each of which contains information about a single unit of analysis or they may reflect aggregate data, as in the case of machine-readable records, that can be used and electronically subdivided into individual case documents.

For computer files, this field contains the number of cases or variables making up the file and, when taken in conjunction with the number of logical records recorded in field 256 (Computer File Characteristics), provides an indication of the extent of the file.

The note is sometimes displayed and/or printed with an introductory phrase that is generated as a display constant based on the first indicator value.
