OPAC Catalog NKUA
After the migration of the NKUA’s bibliographic records to the new cooperative catalog of Hellenic Academic Libraries Link (HEAL-Link) by the name ILSaS (Integrated Library System as a Service), the new OPAC can be used for your searches by the following link:
Note: Possible problems or “unexpected” behavior of OPAC during your searches (due to migration or operation problems) are addressed as quickly as possible with continuous content enrichment and corresponding indexing, functionality, and display level correction.
"Grey literature" Search
When looking for "Grey Literature" materials (graduate dissertations, postgraduate dissertations or PhD theses) please pay attention to the following:
- There is a large number of "Grey Bibliography" publication types in the libraries of the NKUA, most of which have been already listed in the OPAC catalog (several of which may also be available in digital form, noted in a specific field in search results).
- In Pergamos, NKUA’s Institutional Repository, there have been more than 10,000 digital publications registered since 1998, with their number increasing from the mid-2000s onwards. In addition, since the end of 2015, when submitting “grey literature” became mandatory in Pergamos, the number is constantly increasing. If you are interested in such works please search in Pergamos webpage.
Unified Search
The material included in both OPAC and Pergamos (including grey literature) is searchable through the Unified Search Engine available from the NKUA:
