ISAD(G)


ISAD defines the elements that should be included in an archival finding aid. It was approved by the International Council on Archives as an international framework standard to register archival documents produced by corporations, persons and families.

Description

ISAD defines a list of elements and rules for the description of archives and describes the kinds of information that must and should be included in such descriptions. It creates a hierarchy of description that determines what information should be included at what level.
ISAD follows four general principles:
  1. Description begins at the general information and then goes to the specific information
  2. Any information provided should correspond to the level of description
  3. Descriptions should be linked between levels
  4. There should be no repetitions of information in the descriptions
ISAD defines 26 data elements of description, six of which are mandatory:
  1. Reference code: a unique identifier that links to the description
  2. Title: the name of the record
  3. Name of Creator: the entity or individual that created or cultivated the record
  4. Date of Creation
  5. Extent of the Unit of Description
  6. Level of description
The standard provides a framework for a common approach, rather than a rigid format.

History

Previously it had been difficult to access repositories around the world due to the inconsistent description practices among different archives. The need for standardization of archival descriptions became apparent. After initial activities since 1988 supported by UNESCO, a subgroup of the AdHoc Commission on Descriptive Standards discussed the first draft of these standards beginning in 1990. The first version of ISAD was released and adopted by the ICA in 1994.
In 1999, an evaluation of ISAD was conducted in order to determine its effectiveness of describing datasets and to evaluate how it had been being used in data archives. After lengthy research and evaluation, the ICA published a revised version, the second edition, in 2000. Sometimes abbreviated as ISAD2, the revised version remains the current standard today.
ISAD has been adopted as a standard by various members. In the United States, for example, the local implementation of ISAD is .
