The aim of the present research is developing knowledge in the field of open-source code softwares of digitl libraries,and recognition of their strengths, weaknesses, similarities and differences. They include Greenstone, koha, Dspace, My Library, Eprint and OpenBibilo.The existing standards of digital libraries have been investigated and a checklist is prepared so that the best softeware for providing a suitable model could be introduced.This research is a fundamental one. Comparative research method is used to collect the information and describe a feature of each open source code software of digital library.The checklist is used to compare them.According to the checklist, the findings show that among the softwares that are designed as integrated digital library open source code, the highest capability belongs to Koha, My library and Open biblio. Those which have been desgined for digital library materials according to the checklist are: Green- Stone,Dspace,and Eprints.Howeve,from the side of digital library materials, regardless of functional modeles (acquisition, catalouging,OPAC, circulation, serial control) the highest capability belongs to Greenstone,Dspace,Koha, Mylibrary, Eprint and Open biblio.
