The European Grid of Solar Observations (EGSO) is a grid testbed funded by the European Commission's Fifth Framework Programme under its Information Society Technologies (IST) thematic priority. The project started in 2002 and is designed to provide enhanced access to solar and related data around the world. The EGSO grid is composed of two main components, Roles to set up the grid and, catalogs and registries to allow roles to answer users queries. Catalogs are made of lists of observations, events and features (a new service provided by EGSO). Registries are built from these catalogs and organized in order to enhance search capabilities. EGSO is working closely with other virtual observatory (VO) projects in the solar physics and related domains. This includes the US Virtual Solar Observatory (VSO) and the Collaborative Sun-Earth Connector (CoSEC). More recently we have been working with the Virtual Space Plasma Observatory (VSPO) and have contact with the Virtual Heliospheric Observatory (VHO). Through discussions with future missions, and within the new IAU Working Group on ``International Data Access'' (Solar and Heliospheric), the VOs are studying ways of ensuring interoperability from the ``sun to dirt''. This type of integrated access will be particularly important to missions such as STEREO and Living Witha Star. In this paper we will report the current status of EGSO, demonstrate how the catalogs and registries model serves within the user interface, and show how the user can retrieve solar and heliospheric data to match a scientific query. EGSO Release 4 is now being Beta-tested by users and anyone interested should view the Web page detailing all the EGSO capabilities under http://www.egso.org/demo
