The Ballads are arranged under the following heads:--1. Devotion and Morality. 2. History, true and fabulous. 3. Tragedy, viz. murders, executions, judgements of God. 4. State and Times. 5. Love, pleasant. 6. Love, unfortunate. 7. Marriage, cuckoldry. 8. Sea: love, gallantry, and actions. 9. Drinking and good fellowship. 10. Humorous frolics and mirth. The total number of Ballads is 1800, of which 1376 are in black letter. Besides these there are four little duodecimo volumes, lettered as follows: Vol. 1. Penny Merriments. Vol. 2. Penny Witticisms. Vol. 3. Penny Compliments; and Vol. 4. Penny Godlinesses.
Other collections are lettered “Old Novels,” “Loose Plays,” and “Vulgaria.” There are six folio volumes of tracts on the Popish Plot, four quarto volumes of Sea Tracts, and a collection of News-Pamphlets for six years, that is, from January 1st, 1659–60, to January 1st, 1665–66, the time of the commencement of the Gazettes. Pepys was the first person to collect prints and drawings in illustration of London topography. These he left to his nephew, who added to the collection, and two thick folio volumes therefore came to the College with the other treasures.
Pepys’s collections have a special interest, because he collected his books himself, knew all about them, and registered them with loving care. His various catalogues and indexes are marvels of neatness, and living as he did in a pre-bibliographical age, he deserves the greatest credit for the judgment exercised in their production. In the fifth volume of the little collection of books on Shorthand, there is an index of authors, with dates of publication and references to the volume in which each will be found; and the following, which is the title of one of the appendixes to the catalogue, will show how much labour was willingly expended in the production of these helps to research: “A chronological Deductions of the Variations of Stile (to be collected from yᵉ Alphabet of my books) in yᵉ language of England between ann. 700 & yᵉ attempt last made towards its refinement by Sir Philᵖ Sidney in his ‘Arcadia,’ between 1580 and 1590.”
Neatness and the love of accuracy were ruling passions with Pepys, and when a catalogue was filled up with additional entries he had it re-arranged and copied out. On “A Catalogue and Alphabet to my books of Geography and Hydrography, 1693–95,” is the following memorandum: “Before this Index be transcribed far to collect and alphabet the particulars contained in the List of additional Books inserted at the end, and that being done To incorporate both them and the four particular Indexes preceding into the Principal, and so as to unite the whole.”
