This second annual commemoration of the chartering of the North Suburban Library System (NSLS) consists of a speech entitled: "The Suburban System in Metropolitan Library Networks," given by Lowell A. Martin, Professor, School of Library Science, Columbia University and the "Reaction to Dr. Martin's Speech" is by H. G. Johnston. The questions asked and answers given are also included. The NSLS has published and distributed this record of the substance of NSLS Day, 1969, in the belief that it will stimulate a reconsideration of the problems and the promises identified in the program, and will provide an indication of the substance of the commemoration for those who were unable to attend.
