The process followed is:
Clasification of the material using DDC (Dewey Decimal Clasification)
Subject cataloguing using the National Library of Greece Subject Headings and Library of Congress Headings
Descriptive cataloguing according to Anglo-American Cataloguing Rules
Data entry into the automated library system (ABEKT 5.5)
