For the first of these two books the subject-entry is
Himalayas, The:
Workman, F. B., &c. In the ice world of
Himálaya. 1900
and two references will be desirable and necessary,
India:
See also Himalayas.
Mountaineering:
See also Himalayas.
The first of these will insure that a person requiring books upon India in all parts will not overlook those upon the Himalayas, and the second will show that books upon mountain climbing in particular regions are entered under the names of those regions.
As the journey chronicled in the second of these books covered the length and breadth of India, it is entered under the name of the country accordingly, and placed in that sub-division of the subject allotted to books of travel.
India:
Travels and Description.
Workman, F. B., &c. Through town and
jungle. 1904
Any subject-heading comprising a comparatively large number of books is better sub-divided, as it not only facilitates reference, but in a way indicates the character of the books.
Here again title-entries under "In" or "Through" would be useless and wasteful.
For the classified catalogue the first of these books is marked 915.42 (History, Geography and Travels, Asia, India, North-west Provinces, etc.), and the second 915.4 (Travels in India generally). The index-entries are
