The above simplified figure illuminates the essential interconnectedness of the sixteen component encyclopedias of EOLSS.

 In the real world, the various knowledge domains do not exist in isolation from each other. They form an integrated whole, with links in all directions. It is well known that all forms of human knowledge are inter-connected and inter-related. EOLSS mimics this complexity, the automatic inter-connectedness of the various subject categories facilitating navigation through the vast landscape of EOLSS knowledge. This provides the user with an effective and efficient tool to search, navigate and browse through each of the component encyclopedias, through any combination of the sixteen, or through the whole of EOLSS.
