The Croydon Public Library is the centre from which the Photographic Survey and Record of Surrey operates. Surrey took the lead in this important branch of topographical history, and the photographic records of buildings, scenery, and miscellaneous objects of interest now collected in the library comprise some 8,000 prints and lantern-slides, all elaborately classified and indexed for instant reference. Housed along with these is the Regional Survey of Croydon, consisting of maps prepared from actual surveys of the district within fifteen miles’ radius, showing the geology, vegetation, surface utilization, industries, etc. This also is accompanied by photographs. Further, an artist has been commissioned to paint faithful records of architectural or natural features that are likely to perish or be disfigured by modern changes--a thing that will be of priceless value to future generations. This logical extension of the work of preserving local records, minute-books, newspapers, and various fugitive material is being carried on elsewhere, notably at Coventry, Brighton, Northampton, and Nottingham. It deserves the attention of the many local societies that have not yet thrown in their lot with the local library. LIBRARY EXHIBITIONS. Libraries may themselves get up exhibitions or grant hospitality to those organized by kindred bodies. The more the library takes a hand in the preparation, the more can the series of exhibits be related to the appropriate books, and the more effective will such efforts be as aids to popular enlightenment. There is a wide choice of suitable subjects--book-production and its various branches, engraving and other arts, local history and geography, the sciences. The library will be able to supply many of the exhibits from its own stores; usually it is not difficult to borrow useful material from commercial or private sources; and loan exhibits from the State museums are available as nucleus, supplement, or even as forming the whole display. Such exhibitions are placed under the care of keen and intelligent members of the staff, and lectures or demonstrations are given illustrated by the actual objects; the results are enormously ahead of those achieved by the ordinary static exhibition. Lines of reading are pointed out, and books brought into juxtaposition with their subject realities, in a way that even the trained conductor in a museum or picture gallery can hardly compass. Actual experience in organizing and running a number of such exhibitions has left me with no doubt of their popularity or their educational value. When an exhibition illustrating such a subject as the production of a book goes on for three months in the libraries of a London borough, and the average attendance during that period exceeds a thousand a day, we may feel that we are beyond the experimental stage.
