lumes, 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:
