The purpose of this section is to specify the procedure for making changes to the ERIC database after the data involved have been announced in the abstract journals RIE or CIJE. As a matter of general ERIC policy, a document or journal article is not re-announced or re-entered into the database as a new accession for the purpose of accomplishing a change to its record (e.g., a Level of Availability change). It is not desirable to create essentially duplicate records in the database because of the long term adverse effect of such duplicates on retrieval activities. It is preferable to make a change to an existing record and to see that the database files distributed to vendors are eventually updated with such changed records. This manual states the policies for making changes, defines acceptable versus non-acceptable changes, and details the procedures each component of the ERIC system must follow in order to see that different kinds of database changes are accomplished properly.
