What is a Database?

A database is a collection of related data that can be retrieved through searching.

Databases can be bibliographic, namely they can either contain only bibliographic facts (i.e. author, title, volume, publication date) as well as abstracts or provide access to the full text of the article. For further information please refer to the General Guide to Bibliographic Databases. It must be noted that only members of the academic community of the H.O.U. are given access to bibliographic databases through the username and password credentials they have been supplied, for logging in the Educational Portal of the H.O.U.

The HOU Library provides access to Bibliographic Databases:

1. through the Heal-Link portal, (due to the HOU Library's involvement in the Hellenic Academic Libraries Link consortium) and
2. which have been secured by the HOU for its users and are listed below.

  • International Energy Agency (IEA) Open or Close

    The International Energy Agency (ΙΕΑ) is an autonomous organisation which works to ensure reliable, affordable and clean energy for its 28 member countries and beyond. Founded in response to the 1973-74 oil crisis, the IEA’s initial role was to help countries co-ordinate a collective response to major disruptions in oil supply through the release of emergency oil stocks to the markets. While this continues to be a key aspect of its work, the IEA has evolved and expanded providing reliable and unbiased research, statistics, analysis and recommendations. Access to this database is available ONLY LOCALLY by appointment at the Central Library of H.O.U. in Patras as well as the Library of H.O.U. Branch in Athens, for the following collections:

    Important Note: Access to the above collections will be discontinued on April 15th, 2020, except  for “Energy Prices and Taxes Quarterly” which will continue until  August 30th , 2020.


  • Reaxys Open or Close

    Reaxys is an essential tool for all researchers who work on the areas of organic synthesis, pharmaceutical chemistry, synthesis and isolation of natural products, designing bioactive material and compounds and composition of new material.  In this database the contents of three authoritative data resources (Beilstein, Gmelin και Patent Chemistry Database) have been merged. Reaxys also draws data out of (about) 16.000 scientific journals and patents, which go back to the 19th century and over 500.000.000 experimental procedures. It provides information with data regarding synthetic methods, structures and reactions as well as the natural, chemical, spectral, biological and toxicological properties of published compounds. What makes it a unique tool is the opportunities it gives to its users to search chemical structures, formulas, reactions or chemical conversions and the fact that it provides information not just for the (researched) compounds but for their related molecules. Not to mention that one can search for selected chemical patents (US, WO, EP) in the English language.
