In the case of a few of the State libraries, trustees or library commissioners or boards of control have been provided by law, but in others, a joint library committee, composed of members of both houses of the Legislature, has charge of the library interests. This is also the case in the Library of Congress at Washington, where three Senators and three Representatives constitute the Joint Committee of both Houses of Congress on the Library. The membership of this committee, as of all others in Congress, is subject to change biennially. It has been proposed to secure a more permanent and careful supervision of this National Library by adding to the Joint Committee of Congress three or more trustees of eminent qualifications, elected by Congress, as the Regents of the Smithsonian Institution now are, for a longer term of years. The trustees of the British Museum are appointed by the Crown, their tenure of office being for life. In several States the librarian is appointed by the supreme court, as the State libraries are composed more largely of law books, than of miscellaneous literature, and special knowledge of case law, and the principles of jurisprudence, is demanded of the librarian. Where the trustees of a public library are elected by the people, they have in their own hands the power of choosing men who are far above party considerations, and they should exercise it. In no department of life is the maxim--"the tools to the hands that can use them," more important than in the case of librarians and boards of managers of libraries. The value of skilled labor over the unskilled is everywhere recognized in the business of the world, by more certain employment and larger compensation: and why should it not be so in libraries? CHAPTER 18. LIBRARY REGULATIONS. No feature in library administration is more important than the regulations under which the service of the library is conducted. Upon their propriety and regular enforcement depends very much of the utility of the collection.
