Now those are some of the things which might be asserted as the duty of Washington to the country at large. I have touched them as lightly as possible: but there they are. And we may not be able to avoid them. Nay, we seem to be drifting toward them. To some of them we are apparently already committed. There is the building: that in itself seems to commit us. There is equipment. There are books. As regards any national service the federal libraries should be one library. They contain nearly two million volumes. The Library of Congress contains net some 700,000 books and a half million other items. It has for increase (1) deposits under the copyright law, (2) documents acquired through distribution of the federal documents placed at its disposal for exchange--formerly 50 copies of each, now 100, (3) books and society publications acquired by the Smithsonian through its exchanges, (4) miscellaneous gifts and exchanges, and, (5) purchases from appropriations. These have increased from $10,000 a year prior to 1897 to $70,000 for the year 1901-2. Such resources are by no means omnipotent. _No_ resources can make absolutely comprehensive a library starting its deliberate accumulations at the end of the 19th century. Too much material has already been absorbed into collections from which it will never emerge. But universality in scope does not mean absolute comprehensiveness in detail. With its purchasing funds and other resources the Library of Congress bids fair to become the strongest collection in the United States in bibliography, in Americana (omitting the earliest), in political and social science, public administration, jurisprudence. If any American library can secure the documents which will exhibit completely legislation proposed and legislation enacted it should be able to. As depository of the library of the Smithsonian it will have the most important collection--perhaps in the world--of the transactions and proceedings of learned societies; and, adding its own exchanges and subscriptions, of serials in general. With theology it may not especially concern itself nor with philology to the degree appropriate to a university library. Medicine it will leave as a specialty to the library of the Surgeon-General's office, already pre-eminent, Geology to the library of the Geological Survey. Two extremes it may have to abstain from--so far as deliberate purchase is concerned: (1) the books merely popular, (2) the books merely curious. Of the first many will come to it through copyright; of the second many should come through gift. (Perhaps in time the public spirit of American collectors and donors may turn to it as the public spirit of the British turns to the National Library of Great Britain.) Original sources must come to it, if at all, chiefly by gift. Manuscript material relating to American history it has, however, bought, and will buy.
