Catharine's Hall, one hundred and four volumes, of which eighty-five were given by the Founder[296]; and a catalogue of the old library of King's College, dated 1453, one hundred and seventy-four volumes. In these catalogues the books are not directly classed under heads, but arranged roughly, according to subject, in their respective cases[297]. At Peterhouse in 1418 we find a somewhat larger collection, namely, three hundred and eighty volumes, divided among seventeen subjects. The general heading of the catalogue[298] states that it contains "all the books belonging to the house of S. Peter in Cambridge, both those which are chained in the library, those which are divided among the Fellows, and those of which some are intended to be sold, while certain others are laid up in chests within the aforesaid house." This language shews that by the time the catalogue was made the collection had been divided into books for the use of the Fellows (_libri distribuendi_) and books chained in the library (_libri cathenati in libraria_); in other words, into a lending library and a library of reference. We are not told how this division had been made, or at what time; but it is evident that by 1418 it had become permanent, and no longer depended on the tastes or studies of the Fellows. There was one set of books for them to select from, and another for them to refer to; but the two were quite distinct[299]. In the next place I will analyse the catalogue in order to shew what subjects were represented, and how many volumes there were in each. And first of the contents of the library of reference:
