The purpose of this paper is to study the effect of the national library standards, beginning with a synopsis of the 1945 version up to the latest revision of 1969, and to show how the addition of audiovisuals, or non-print materials, has affected the connotation of the library or librarian. The definition or explanation of the library becomes more complex and the needed educational requirements of the school librarian have increased enormously. Requirements have been expanded to include knowledge in three basic fields: library science, professional education and audiovisuals -- yet at the same time highly specialized as to subject, level and type. One section of the paper includes certification requirements for school librarians as received from each State Department of Education. Comparison of requirements in each state plus studies relating to past and present education of school librarians have produced several suggestions in the final section. Hopefully a unifying effect from the colleges and universities, national associations, and the State Departments of Education can achieve the highest standards available for tomorrow's school librarian-media specialist and audiovisual specialist.
