The function of the department is to give assistance to readers in their search for information or for books. Readers should apply here for aid in the use of the catalogue or for direction in finding the resources of the library upon any subject under investigation. The Reference Department has supervision over reference books, periodicals, maps, United States government documents, university archives and publications, and the “New Books” shelf. =Reading Room Collection.=--Reference books are shelved in the Reading Room. Dictionaries, encyclopaedias, yearbooks, indexes, and bibliographies will be found in the two floor cases (A and B) directly back of the center desk. The collection of atlases will be found in the atlas case (C). Other works of reference, together with a collection of general literature, are arranged by subjects in the wall cases around the room. Those reclassified by the Library of Congress system begin with case 1 to the left as one enters, and the books arranged by the Rowell classification follow them. The Mary Lake collection of English and American literature occupies cases 112 to 116. =Periodicals.=--The library receives approximately 8000 serials. The current numbers of 1200 of these are placed on the shelves around the Periodical Room and in the adjoining stack. These periodicals are grouped by subjects. The general magazines are in cases 1 to 4, art journals in case 5, etc. A directory of the location of subjects will be found on the bulletin board. A collection of the 296 sets of bound periodicals most frequently called for is shelved in alphabetical order in the adjoining stack room or Annex, to which readers have free access.
