an edifice or apartment destined for holding a considerable number of books placed regularly on shelves; or, the books themselves lodged in it.

The first who erected a library at Athens was the tyrant Pisistratus, which was transported by Xerxes into Persia, and afterwards brought back by Seleucus Nicator to Athens. Plutarch says, that under Eumenes there was a library at Pergamus that contained 200,000 books. That of Ptolemy Philadelphus, according to A. Gellius, contained 700,000, which were all burnt by Caesar's soldiers. Constantine and his successors erected a magnificent one at Constantinople, which in the eighth century contained 300,000 volumes; and among the rest, one in which the Iliad and Odyssey were written in letters of gold, on the guts of a serpent: but this library was burnt by order of Leo Isaurus. The most celebrated libraries of ancient Rome were the Ulpian and the Palatine, and in modern Rome, that of the Vatican. The foundation of the Vatican library was laid by pope Nicholas, in the year 1450; it was afterwards destroyed in the sacking of Rome by the confable of Bourbon, and restored by pope Sixtus V. and has been considerably enriched with the ruins of that of Heidelberg, plundered by count Tilly in 1682. One of the most complete libraries in Europe, is that erected by Cosmo de Medicis; though it is now exceeded by that of the French king, which was begun by Francis I. augmented by cardinal Richelieu, and completed by M. Colbert. The emperor's library at Vienna, according to Lambecius, consists of 80,000 volumes, and 15,940 curious medals. The Bodleian library at Oxford exceeds that of any university in Europe, and even those of any of the sovereigns of Europe, except the emperors and the French kings, which are each of them older by 100 years. It was first opened in 1602, and has since been increased by a great number of benefactors; indeed, the Medicean library, that of Bessarion at Venice, and those just mentioned, exceed it in Greek manuscripts; but it outdoes them all in Oriental manuscripts; and as to printed books, the Ambrosian at Milan, and that at Wolfenbuttle, are two of the most famous, and yet both are inferior to the Bodleian. The Cotton library consists wholly of manuscripts, particularly of such as relate to the history and antiquities of Britain; which, as they are now bound, make about 1000 volumes.

In Edinburgh there is a good library belonging to the university, well furnished with books; which are kept in good order. There is also a noble library of books and manuscripts belonging to the faculty of Advocates. See Advocate.
