It may be of interest that in BS8723-1:2005 we have used the term
"documents" as a label for any kind of resources. The relevant
definition reads thus:

    "document

    item that can be classified or indexed in order that it may be
    retrieved

    NOTE  This definition refers not only to written and printed
    materials in paper or microform versions (for example, books,
    journals, diagrams, maps), but also to non-printed media,
    machine-readable and digitized records, Internet and intranet
    resources, films, sound recordings, people and organizations as
    knowledge resources, buildings, sites, monuments, three-dimensional
    objects or realia; and to collections of such items or parts of such
    items."

This is perhaps another illustration of the distinction between a
concept and the term which has been chosen to label it. I think that the
scope note above covers all the "non-document resources" that Richard
refers to.
