A subcollection is a group of collection items that belong together. Sometimes because it involves the same type of material — photographs, objects, archival records. Sometimes because the material comes from one person, family or organisation and has been preserved as a whole.
In archival terms, that second type is called an archive, and the person or organisation that built it up the archive creator. Anyone looking through someone’s archive sees not loose items but a life or an organisation captured in documents: letters, reports, photographs, minutes. It is precisely the connection between those items that makes them meaningful.
Below are first the four main groups into which the collection is divided, and then a number of the archives the museum manages.
