124. Make a form-entry of encyclopædias, indexes, and works of similar practical form, the general ones under the headings Encyclopædias, etc., the special ones in groups under their appropriate subjects.
Thus an agricultural dictionary will not be entered under Dictionaries, but under Agriculture, in a little division Dictionaries. Now and then some one asks for “a grammar,” “the dictionary.” It does not follow that it would be well to jumble together, under a form-heading, Grammars or Dictionaries, all grammars and lexicons in all languages. Those who inquire so vaguely must be made to state their wishes more definitely. The cataloguer does his part if he inserts a note under such headings explanatory of the practice of the catalogue; as
Grammar. [First a list of works on general grammar, then]
Note. For grammars of any language, see the name of the language.
V. ANALYSIS.
125. Enter in full every work, forming a part of a set, which fills a whole volume or several volumes.
Ex. Colombo, C. Select letters rel. to his four voyages to the New World; tr. and ed. by R. H. Major. London, 1847. 8º. (Vol. 2 of the Hakluyt Soc.)
126. Enter analytically, that is without imprint—
a. Every work, forming part of a set, which has a separate title-page and paging, but forms only part of a volume of the set.
Ex. Fairholt, F. W. The civic garland; songs from London pageants, with introd. and notes. (In Percy Society, v. 19. 1845.)
