The looking up of references on domestic science, the boy scouts, or the fireless cooker and other similar subjects is supposed to be the work of the public library. It may be that notwithstanding the emphasis placed by the public library on its reference work, and work with schools, the college by its extension service is going to enter this field and do at long range what the public library is not doing for its own local community. If there is sufficient demand from the rural districts for the service given by the public discussion and information divisions of the extension work (as it is often called) it is certainly a strong argument in favor of the extension of the public library service over the counties or townships as is now being done in several states. There is a good field here for co-operation between the local library, the organized library interests of the state, the college library and the extension service of the college or university. An interesting feature of the work of the extension department at Purdue university is the combination of the printed list of books, the sample library, and the actual sale of books to the farmers. Some months ago by consultation with members of the station staff and actual examination of many volumes, a list of about 75 titles relating to agriculture, was compiled and printed. Several sets of these volumes were then obtained from the publishers, and arrangements made with them for mail orders of these books at certain discounts. The printed lists and sample volumes were taken to county fairs, institutes, farmers short courses, and on special trains. The lists were distributed, the books shown to the farmer, and his order taken on the spot at list price. Many orders come in later by mail. There is good psychology in this method of getting the book to the farmer. He can examine the book for himself, give the necessary weight to the recommendation of the man in charge, and having confidence in the university as represented by the extension department, he trusts it with his money. During the year and a half that this plan has been in operation 1,350 volumes have been placed in the hands of farmers in the state and the sales have been as high as $475 in a month. Some may see objections to this method of book distribution and there are dangers that must be guarded against, but in Indiana it is regarded as firmly established.
