This last calls for the reference
Hildebrand. See Gregory VII., Pope.
The lives of popes, or any other works dealing with them as individuals, do not need references from their family names, because these names are merged when the bearers are raised to the pontificate, and it is unlikely that anyone will look under Pecci for Leo XIII. Two useful general references can be added
Roman Catholic Church.
See also Popes.

See also the names of Popes as Gregory VII.,

These references assume that there are books in the catalogue upon the popes generally.
It will have been observed in passing that both these books, and that upon Prince Henry the Navigator, in the previous examples, belong to series, the titles of which are contained in the entries. They are usually noticed for headings in the dictionary catalogue, as it can be made to furnish a list of the volumes in a library, belonging to a series, under the name of the series. As such a list is not intended to serve as a makeshift form of subject-entry, the first word (articles excepted) of the title of the series is taken for the entry-word of the heading, as Heroes of the Nations, Public Men of To-day, Epochs of Church History, capitals being used to denote that these are special names. There are three ways of entering under a series heading, viz., (1) by the authors' names arranged in alphabetical order, as
| Heroes of the Nations; ed. by Evelyn Abbott: | |
| Beazley, C. R. Prince Henry the Navigator, 1895 | 923.9 |
(2) by the subject, especially in a series of a biographical or personal nature, as
| Public Men of To-day: | |
| Leo XIII., by J. McCarthy. 1896 | 922.21 |
