This report provides a list of 26,654 Level 3 documents, i.e., documents that have been announced in Resources in Education (RIE) which the authors have not granted ERIC permission to reproduce in either microfiche (Level 2) or microfiche or paper copy (Level 1). These documents are neither included in the ERIC Microfiche Collection nor available from the ERIC Document Reproduction Service (EDRS). The purpose of this list is to provide users with a cumulative list, by ERIC document number (ED), covering the period from November 1966 through December 1988, of all those items that are not available through the ERIC system. It is noted that: (1) the list of Level 3 accessions--numbered in succeeding order--can be used to validate a missing microfiche, i.e., to prove that it is legitimately missing rather than lost or misfiled; (2) the list can also be used to validate document orders going to EDRS; (3) no items on this list can be ordered from EDRS, since EDRS has neither the master microfiche nor permission to reproduce them; and (4) all Level 3 accessions carry a note in the announcement in RIE that specifies an external source of availability. A summary table which precedes the master list of Level 3 documents provides the number of the accessions and percentage of each level of availability of ERIC documents for each year of the ERIC file for the period covered.
