A performance is then a special kind of cultural artifact that cannot be curated in libraries and museums but what these cultural institutions do curate are materials that are related to performances and are most usually found in theatrical collections. It may concern material that was probably used in a performance or it may witness how it came into being. The image shows a real-life example from the National Library of France of performance related things and documents.
The National Library of France has in its collection a set of physical objects that are related with a specific performance, the Sergei Radlov’s “King Lear” performed at the Moscow State Jewish Theatre in 1935. These objects are a manuscript with comments on a specific performance, the manuscript music score used in that performance, a wooden model used for the stage setting, the text of the play, photographs taken during the performance etc. These objects are associated either with the concept of the performance, the work (F20), the plan of the performance (F25), or the event itself (F31).
A theatrical collection may also consist of prompter books which provide glimpses of performance plans, video/sound recordings, press clippings that make statements about performance works, posters advertising performances, 3D models of theatre scenery, costume sketches etc.
