The Press has also published very numerous reproductions of works of art of all kinds, partly by way of illustrated catalogues of special collections or _genres_ (such as the three folio volumes of Oxford Drawings by the old masters, the numerous coin catalogues, and the cheap collection of British Historical Portraits in half-tone); partly in the form of profusely illustrated monographs, which moreover are all scientific works by experts and not mere collections of pretty pictures with illustrative letterpress. These works are of great importance to students and collectors, and a select list is appended: Head’s _Historia Numorum_, Gardner’s _Ancient Coinage_, Beazley’s and other books on Greek Vases, Hill’s _Renaissance Medals_, Dalton’s _Byzantine Art_, Maunde Thompson’s _Palaeography_, Murray’s _History of Chess_, ffoulkes’s _Armour and Weapons_, Rivoira’s _Moslem Architecture_, Vincent Smith’s _Fine Art in India_, Sir Aurel Stein’s _Khotan_ and _Serindia_ and other special works on Eastern Art, the important series of monographs on English Church Art written or edited by the late Francis Bond, with his comprehensive _Introduction to English Church Architecture_ in two volumes, and many more too numerous to cite, particularly the great wealth of British Museum catalogues. A very welcome recent accession to the catalogue is supplied by the sumptuous monographs on Italian Masters produced by the Harvard and Princeton University Presses. The use of illustration is, however, by no means confined to facsimiles and works on the arts. The modern productions of the Press have made an increasing use of illustration both as an embellishment and as a medium of information. School-books in particular are now lavishly illustrated with portraits, maps, diagrams, and other reproductions, often either of modern photographs or of old cuts and engravings carefully chosen, so that the actual men and things of former times may be faithfully mirrored. The Press prints for the British Museum and other London collections, as well as for the Ashmolean Museum at Oxford, very large numbers of postcards in collotype, by means of which a knowledge of our national art treasures is being widely spread. § 5. _Official Publications_
