The aim of the Collections Trust Documentation planning pack is to assist museums to produce their own documentation plans. The guidelines contained in the pack can be used for all types of documentation planning; they are not intended as the only way to produce a documentation plan and are specifically to help the documentation planning process as required by UK Museum Accreditation Scheme.
Here you can find further resources to help with the Spectrum procedure Documentation planning. For the procedure itself follow this link.
This resource explores re-numbering, suggests why it is a poor use of resources, and gives some examples of numbering problems and their solutions.
