Ex. The hystorie of the saints would be entered—
History.] The hystorie of the saints.
We enter under the common spelling (1) in order to get all editions of a work together, (2) because the reader can not be expected to know exactly how the word is misspelled in the title, and will generally look first under the correct spelling.
Of two spellings equally correct, choose one and refer from the other.
80. When the first word of a title is in an oblique case, use the nominative as a heading.
Ex. Put Monumentorum antiquae sculpturae quae supersunt under Monumenta.
81. If the title has various forms, refer from any that differ enough to affect the alphabetical order.
See the example in § [68].
82. Modern anonymous works whose titles are changed in different editions may be entered under the first, with a reference under the later; but the most satisfactory method is to enter in full in both places.
83. Anonymous works that change their titles in successive volumes are to be entered under the first title, with a reference from the later, unless the greater part of the work has the later title, or the whole is much better known by the later title, in which case entry should be made under that. {43}
