It is a unique identifier given to a document that has been reproduced and made available for circulation to educators and researchers. The purpose of the EDRS number is to provide a standardized way to cite and locate a document that may not be available in its original form. This number consists of a series of numbers and letters and includes information about the author, year of publication, and other relevant details. The EDRS number can be used to request a copy of the document from the Document Reproduction Service or to locate it in a library or online database.
