At the outset of UN and UNESCO, "Decade of Education for Sustainable Development - 2005-2014", we wish to introduce to you the Encyclopedia of Life Support Systems (EOLSS). The EOLSS On-line, an integrated compendium of twenty stand alone Encyclopedias in synergetic synthesis, is the result of several years of dedicated work of a global team of distinguished scholars, organized under the auspices of the UNESCO. It is equivalent to about 600 volumes with contributions from thousands of scholars from over 100 countries and edited by over 300 subject experts.

The EOLSS On-line has emerged as the largest and the most authoritative source of thematically organized current knowledge. Users will find the EOLSS On-line a convenient reference to help them in their chosen field of specialization and support their efforts in gaining a holistic understanding of many current problems through interdisciplinary subjects and transdisciplinary pathways forged across disciplines.

The EOLSS On-line is rapidly becoming the most sought-after reference site in the world.

UNESCO-EOLSS is an Integrated Compendium of twenty Encyclopedias. (A virtual dynamic library equivalent to about 235 Themes).
