Scope note: This class comprises works that conceptualise the capturing of features of perdurants. The characteristics of the manifestation of a recording work are those of the product of the capture process. The characteristics of any other works recorded are distinct from those of the recording work itself. In the case where the recorded perdurant expresses some Work, the respective instance of F21 is also an F16 Container Work. The concept of recording is not necessarily linked to the use of modern devices that allow for mechanical recording, such as tape recorders or cameras. However, in practice, library catalogues tend to regard as recordings only the products of such mechanical devices. But the concept of recording is very much linked to the notion that there is something that is recorded. In general, photographs or animated images are not to be regarded as instances of F21 Recording Work just because of the use of the medium, but simply as instances of F1 Work (or F15 Complex Work). Only such photographs and animated images that can be used as documentation are to be regarded as recordings. Examples: -The concept of recording the Swedish 17th century warship Vasa in August 1959 to April 1961. -The concept of documenting the Live Aid concerts July 13, 1985, London, Philadelphia, Sydney and Moscow. -The concept of making a photograph of the three Allied leaders at Yalta in February 1945. -Oceania Project’s concept of making a large digital acoustic data archive dedicated to East Australian humpback whale songs. -Concept of recording Louise Bourgeois’s activity in the documentary movie entitled ‘Louise Bourgeois: The Spider, the Mistress, and the Tangerine’.
