5 Manifestation description

Follow FRBR in considering a manifestation to be the physical or virtual embodiment of an expression of a work.

Changes in physical form create a new manifestation of the same expression of the same work. Such changes in physical form include changes affecting display characteristics (e.g., a change in typeface, size of font, page layout, etc.), changes in physical medium (e.g., a change from paper to microfilm as the medium of conveyance), and changes in the container (e.g., a change from cassette to cartridge as the container for a tape recording).

Where the production process involves a publisher, producer, distributor, etc., and there are changes signaled in the product that are related to publication, marketing, etc. (e.g., a change in publisher or distributor, repackaging, etc.), a new manifestation is the result.

If the manifestation is already contained in the catalog, use the manifestation record already created.

Manifestation of a manifestation

It is possible to have a manifestation that consists of a reproduction in a different format or a new distribution (e.g., facsimile publication) of a particular previously existing manifestation. This relationship (manifestation of a manifestation) may be indicated by means of a note either composed by the cataloger or transcribed from an item being cataloged and placed in quotation marks.

Related manifestations

Two or more formats may be simultaneously published, released or distributed as alternate formats of the same content. This relationship (related manifestations) may be indicated by means of a note either composed by the cataloger or transcribed from an item being cataloged and placed in quotation marks.

Demonstrating relationships among manifestations of the same expression

In order to indicate the relationship among two or more manifestations, include one or more relator terms from the following list. Choose the most specific term, if possible. If none of these terms apply, it is permissible but not required that the cataloger compose a term to describe the relationship among two or more manifestations [type of data: composed data—controlled terms]:

alternate
facsimile
reproduction
