That the experiment station workers should have readily available as complete a collection as possible of the "official agricultural literature," both American and foreign, seems most desirable if not imperative. Whether this material should be filed in the station library or in the college library and to what extent it should be duplicated is a matter for each institution to decide, according to its needs and local conditions. In the case of an experiment station located on the college campus and near enough to the college or university for the station workers to use the general library, there is still much to be said in favor of a separate reference and reading room for the experiment station staff with an assistant in charge, the collection consisting principally of the "official agricultural literature," a selected list of current periodicals and a good selection of reference books of special interest in experiment station work. The ideal plan would be for this room to adjoin the university library like a seminar room. If it is not feasible on account of distance for the experiment station workers to have the collection next to the general library, then it should of course be in the experiment station building or agricultural hall. Libraries of the second or departmental type,--namely, where the college of agriculture and the experiment station collections are combined, contain in general all the library resources of the institution along purely agricultural lines, including the "official agricultural literature," and in addition a fairly complete collection in the sciences relating to agriculture. Such libraries have a two-fold purpose. They must supply the needs of the professors and scientists in connection with their investigations and in addition must serve the students of the agricultural college. If the college of agriculture and the experiment station are some distance from the university,--so far as to make frequent consultation of the university library impracticable, there is no question but that the college of agriculture and the experiment station ought to have a separate library for their especial needs. If on the other hand they are near enough to the university library to make it feasible for the professors and scientists to use it frequently, it is an open question whether it is wise to separate the agricultural collections. It is then a question of a central library versus a departmental or special library. The nearer the college of agriculture library is to the university library, the more intensive should its collections become.
