ANKOS (The Anatolian University Libraries Consortium) established Open Access and the institutional Repositories Working Group(OAIRWG) in order to raise awareness on Open Access (OA) and Institutional Repositories (IRs) among information Professionals in Turkey. Ankara University is one of the first Open Access initiatives in Turkey. Over seven hundred and fifty scientific papers produced by faculty members have been self-archived (http://acikarsiv.ankara.edu.tr/) and made accessible to public since the beginning of 2006. The ‘Hacettepe University Electronic Theses Project’ has been carried to make the full-texts of graduate theses and dissertations accessible through the internet. In September 2003, The Middle East Technical University Library Theses and Dissertation Archive was established and since then students have been submitting their theses in electronic format to their IRs’ system. Because of these good practices, We started to establish our own institutional repositories. Istanbul Ayd?n University Institutional Repositorie (IAUIR) contains valuable scientific contents like articles, proceedings, visual materials, poster sessions, books and book chapters etc.
