Some of the professional impressions gained from a month in the United States by a British librarian are summarized in this report. Six library school libraries and the Library of the American Library Association were visited. The greater emphasis on bibliographic and reference material allows students in the United States more frequent access to works known to British students only by name. The relationship between the library school faculty, the library school library and the main university library are considered to be more dependent upon the personalities of those involved than on formal administrative relationships. Based on the few public libraries visited, it appeared that stock provision, particularly of reference tools, is more generous than it would be in British libraries. The Library of Congress and the John Crear Library are compared with their closest counterparts in Britain. In the area of library administration, three things were particularly noted: the long opening hours, the wealth of guides and bibliographies issued, and the richness of the stocks. The final section of this report gives impressions of the construction of some of the new library buildings. A summary of the visits made is appended. (Author/NH)
