The building of this library is recorded in four separate account-rolls extending from the beginning of the first year of Richard II. to the third year of the same king, that is from 1377 to 1379. From these documents it appears that the building cost £462. 1s. 11½d.

From this first construction to the beginning of the sixteenth century—a space of 125 years—the accounts furnish us with no information; but, from what we learn afterwards, it would appear that the internal walls were unplastered, that the roof-timbers were unprotected, and that the only light was admitted through the narrow lancet windows.

In 1502-3 the panel-work (celatura) on the roof of the west library was put up at a cost of £27. 6s. 0d. The account contains also a charge for painting the bosses (nodi) at the intersection of the moldings that separate the panels. Mr Henderson points out that these ornaments prove the existing ceiling to be that put up in 1503; for among them are the Tudor Rose, the dolphin of Fitzjames (Warden 1483-1507). and the Royal Arms used from Henry IV. to Elizabeth, but altered by James I.

After this another long interval occurs during which no work done to the library is recorded; but in 1623 the south room was taken in hand, and the changes introduced into it were so extensive that it is referred to in the accounts as New Library (Nova Bibliotheca) a name which it still retains.

In the first place the room at the east end ([fig. 81]) was thrown into it, and the oriel window constructed, together with the two large dormers on the side next the court ([fig. 80]). These works, by which light was so largely increased, prove how gloomy the library must have been before they were undertaken. Next, after important repairs to the walls and floor, and the construction of the decorative plaster-work at the east end, the old bookcases were sold, and Benet the joiner supplied twenty new cases and one half-case. The only old case remaining is, by tradition, the half-case against the screen on the north side as one enters from the vestibule.

It is therefore certain that the cases and seats in the south room date from 1623. It is unfortunately equally certain that we know nothing about the date of those in the west room; and we are therefore unable to say whether the cases in the south room were copied from them in 1623, or whether the reverse process took place at some unknown date. If we adopt the pleasing theory that in the west room we have very early cases, constructed possibly when the library was built, we must still admit that these relics of a remote past have been altered at some subsequent period, so as to be brought into conformity with the cases in the south room; for the cornices and the frames for the titles are precisely similar in the two rooms.

The difference between the two sets of cases in the method of chaining, to which attention has been already drawn, may bear on the question of date. As time went on chaining would be modified in the direction of simplicity; and to replace a single central bar by two lateral ones is a step towards this, for under such conditions the addition or removal of a book would entail less displacement. Further, it must be recognised that these cases, whether extremely ancient or comparatively modern, differ in many particulars from those to be met with elsewhere. They are lighter, narrower and more elegant. Again, when the ground-plan of the library is considered ([fig. 81]) it will be seen that their ends occupy nearly the whole space between a pair of windows. In other examples of the stall-system this is not the case.

The only explanation I have to offer for the whole difficulty is the following. The library was constructed for the lectern-system, with wall-spaces not more than 2 ft. wide, and was so fitted up. When books had become numerous the western library was taken in hand, and the lecterns altered into stalls, the single central bar being retained. At the same time, in all probability, the dormers were inserted. It is remarkable that these changes should not be recorded in the accounts, but possibly they were carried out as the result of a special benefaction[336]. In 1623 the stalls which had been placed in the west room, having been found convenient, were copied for the south room.

I will in the next place briefly notice the distinctive points of the other examples of the stall-system in Oxford.

At S. John Baptist's College the library was built in 1596, and we may presume was fitted up soon afterwards, as Wood records numerous donations of books in the years immediately succeeding, and the appointment of a keeper to take charge of them in 1603[337]. This library, on the first floor of the south side of the second quadrangle, is 112 feet long by 26 feet wide, with eight windows of two lights in each wall. The bookcases, of which there are eight on each side between the windows, with a half-case against the west wall, are rather larger than those at Corpus Christi College, being 10 feet high, and 2 feet 6 inches wide. They have a classical cornice and terminal pediment. The titles of the subjects are painted at the tops of the stalls as at Merton College. A few traces of chaining are still to be detected. The desks have not been altered. Each is in two divisions, as at Corpus, separated by a central bracket, and it has the slit to admit the chains. The long iron hinges are evidently original. The seats resemble those at Corpus.
