I think 773 field (Host Item Entry) can be used as a pair for 774 field.
USMARC Format for Bibliographic Data states that 773 field is used for:

"Information concerning the host item for the component part/subunit
(Leader/07, Bibliographic level, code a, b, or d) that is described in the
record (vertical relationship). When a note is generated from this field,
the introductory term In may be generated based on the field tag."

Proposal 96-04 discussed that "alternative is given to define a new field
774 for Constituent Unit Entry and remove the restriction in field 773 (Host
Item Entry) that it be used only for titles that are subunits or component
parts, i.e., physically contained in the host" and this was approved.

Subject: field 774 question


I would like to ask your advice concerning the description of folders of
photographs and drawings.

The folders are units to be described themselves as they contain important
        information contemporary to the photoes.

The importance of some individual photoes justifies for us to
        catalogue some but not all of them separately.

We have been wondering on the appropriate linking fields to be used in this
        situation:

        one suggestion was to use 787-787 pairs (with an explanatory 580);
                the reason why we were not altogether happy with this
                solution is that it does not express the hierarchical
                relationship between the folder and the photoes.

        the pairs expressing hierarchical relationships (760-762 and
770-772)
                seem to be a bit out of context here


        then we turned to 774 field which clearly indicate different levels
                in the hierarchy; but it seems to be used only in records of
                the higher level documents to describe the constituent parts
                (such as volumes to a multivolume book). Is there a "pair"
                of this field to express the other direction of the
                relationship referring to the folder in the records of the
                photoes?

Please, share your experience in cataloging like material with us.

Thank you very much.

Best regards
