Eighty-three volumes of the works of William Williams of Pantycelyn. There are also substantial collections of pamphlets, elegies, almanacs, ballads, satires and tracts that Davies had collected. Bourdillon Collection In 1922 the National Library of Wales purchased the collection of French medieval literary texts and early illustrated books that had been assembled by Francis William Bourdillon (1852–1921). Bourdillon's library included twenty-three editions of the Roman de la Rose and an important group of works on the Arthurian legend. The 6,178 printed volumes include sixty-six incunabula, 180 English short title catalogue books (1475–1800), including twenty-five STC and fifty Wing books. Further, there are 320 volumes that were printed in continental Europe during the sixteenth century, and another 260 items which date from the 17th and 18th centuries. Incunabula The National Library has a collection of about 250 incunabula, which are predominantly German, Italian and French imprints.

The third is another copy of the Polychronicon, printed by Caxton's successor Wynkyn de Worde in 1495. Nine specimens of early printed books (three German, five Italian and one printed in Ghent) were deposited by Lord Harlech between 1938 and 1941. Other notable incunabula in the Library are the Astronomica by Marcus Manilius (1474) with illuminated initials and borders, and Hartmann Schedel's Liber Chronicarum (1493).
