In both rooms each case has a picturesque enrichment at the end of the standard above the cornice, and a small oblong frame just below it to contain the general title of the books within the case. The west room is devoted to LIBRI ARTIUM, with the exception of the three cases and the half-case at the north end of the east side, which are marked CODICES MSS. These are protected by latticed doors of wood. In the south room the cases on the south side are all lettered L. THEOLOGIAE; on the north side the first three are lettered L. MEDICINAE; the next L. MEDIC. IURISPP. and the last five L. IURIS PRVDENTIAE. In this room the last cases at the east end on each side have latticed doors like those on the corresponding cases in the west room. 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 L462. 1_s._ 11 1/2_d._ 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 L27. 6_s._ 0_d._ 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.
