All these books are on the plots, and should come together. At present anyone looking at the entry would suppose that there was only one book on the plots of the plays in the library.
Another way of making the references may be set out thus:—
Shakespeare:
Life: Chalmers, De Quincey, Fullom
(1864), Halliwell (1848), Knight
(1842), Skottowe (1824).
—— S. and his Contemporaries: Nares
(1822).
—— S. and his Times: Drake (1817).
Plots of his Plays: Lennox (1753),
Simrock (1850), Skottowe (1824).
Not only does the second plan take up less space, but it is also the more convenient, as giving the required information in the clearest manner.
All references should be in English,[29] and the subject of the book should be used for the reference rather than the often periphrastic form of the title. Thus, in making a subject reference for the following book:—
Mudie (Robert). The Feathered Tribes of the British Islands. 1834. 2 vols.
—the reference must be from "Birds" or "Ornithology," as it will be useless to refer from "Feathered Tribes."
