We have the choice of another heading, viz., "Women"; and as there will certainly be other books in a reasonably sized library upon the labour and wages aspects of the question, it would be a waste of space to give double entries (under both headings), therefore we proceed to put the matter right by a reference—
Women:
See also Labour (Women's work).
If we consider that the book has some bearing, as this has, upon the social question in general, sweating, and poverty, we add See also references under any headings adopted for these subjects.
Social Question, The:
See also Labour.
Sweating:
See also Labour.
Poor:
See also Labour.
When the time for printing arrives, if the completed catalogue has no books entered under any of these headings, the See also reference must either be withdrawn altogether or converted into a See reference. For example, the reference from "Sweating" might be given as
Sweating. See Labour.
upon the supposition that books solely upon this aspect of the labour question might be better placed under the more general heading, though this is somewhat against the rule for specific entry. The difference between these two forms of reference may again be emphasised. The See reference is intended to prevent books being entered under the subject-heading referred from in order that they be placed under the heading referred to; the See also reference is an appendix to a subject-heading, under which books relating to the subject in general are entered, and is meant to direct to lesser or related divisions of the same subject.
The scope of the inquiry of the book is local and has an important bearing upon social conditions in Birmingham, which must be taken into account, therefore an entry is given
Birmingham:
Social, &c. Conditions.
Cadbury, E., &c. Women's work and wages.
