Humboldt, K: W:, Freiherr v. Briefwechsel. See Schiller, J: C. F: v., and Humboldt, K: W: v. But see § [240].
When countries are joint authors it is better to make full entries under each and arrange them as if the country under consideration were the only one. Each country puts its own name first in its own edition of a joint work; and the arrangement proposed avoids an additional complexity under countries, which are confusing enough at the best.
Whether the joint authorship appears in the title or not should make no difference in the mode of entry; if one name appears on the title, that should be chosen for the entry; if none, take the most important.
4. When double headings are used distinguish between joint authors of one work and two authors of separate works joined in one volume. In the latter case, if there is no collective title, the heading should be the name of the first author alone and an analytical reference should be made from the second. (See § [58] b.)
Ex. “The works of Shelley and Keats” would be entered in full under Shelley (both names being mentioned in the title, but Shelley alone in the heading), and analytically (§ [127]) under Keats. In such cases a double heading would often mislead.
5. For university theses or dissertations Dziatzko gives the following rules:
- I. Until about 1750
- a Unless the respondent is known to be the “auctor” (“auctor et respondens,” “scriptor,” etc.) enter under the name of the præses, without reference.
- b If the respondent is “auctor” enter under him, with reference from the præses.
- II. After 1750 enter under the respondent, unless it is known that the præses is the author, when his name will be the heading. In neither case refer from the other name.
For universities where the old custom was kept up beyond 1750, as the Swedish, Rule I applies till the change was made. {18}
Where there are two respondents, neither specified as author, enter under the first, without reference from the second.
6. Enter pseudonymous works generally under the author’s real name, when it is known, with a reference from the pseudonym; but make the entry under the pseudonym, with a reference from the real name, when the writer is better known by the false name.
