A thoroughly efficient Reference Department cannot fail to render first-class service to any community, but it must be remembered that the very nature of reference work renders compulsory a high state of efficiency. A comparison of the duties of reference and lending staffs will assist one to visualise the special requirements of the department more clearly. In surveying the various reference duties, consider the advisability of allowing certain books to be taken out on loan, the extent to which you would allow access to the stock, the disposition of the various classes, and make a special note of the books which are essential for the quick-reference section (_see page 72_). Note also the means (indexing, etc.) necessary to render all information immediately accessible. Useful work is done in many places by Information Bureaux. Note the information these are expected to supply, the preparation necessary to equip them for the purpose they serve, and their possible development. The success of a series of lectures depends chiefly on their proper organization. See what arrangements are essential to their success, and the best methods of ensuring that the interest created results in increased use being made of the library. University Extension and other movements, by wise co-operation, can serve the library in this respect. Study the various points in connection with the formation of Reading Circles, and the efforts required in order to guarantee their retention as a live factor contributing to the success of the library. The Central Library for Students renders assistance to libraries. Study the nature of this, the conditions and the potentiality of the Library as the centre of a more ambitious scheme of a national reservoir library for the distribution of certain classes of books. Consider the utility of the Bulletin, the information it should contain, the policy of including advertisements to defray cost, and the various points in connection with its production. Several libraries issue bulletins (_see page 111_). If possible, obtain copies of these. Up to the present the usual publicity methods have not been called to the service of the library to the same extent in England as in America. View the question from all aspects, note what is at present being done by various libraries, and consider the numerous suggestions which have been made for the expansion of this form of activity. Note the importance of good shelf and stack guiding as aids to readers. (_See pages 84-5 and read the articles given under the names of Coutts, Savage and Stewart._) READING LIST. GENERAL.
