The key terms used in compiling this collection are "Program Budgeting,""Program Planning," and "Systems Approach." The documents concern both the philosophies and the practices of PPBS, and include models, procedures manuals, and bibliographies. The following information is presented for each document: personal or institutional author, title, place of publication, publisher, publication date, number of pages, ERIC document ("ED") number, price of the document if it is available from the ERIC Document Reproduction Service, and the abstract. The documents are numbered and listed alphabetically by the authors' last names. A subject index refers to the document listing number. The subject terms, arranged in alphabetical order, are identical to those contained in the subject index of RIE. (Author)
