An information system “Thermal Constants of Substances” based on the printed version of the corresponding reference book (Thermal Constants of Substances: Vol. 1-10 / Chief Ed. V.P. Glushko.- M.: VINITI, 1965-1982) has been developed. The work over the printed version of the reference book was accomplished by a group of more than 80 experts in field of chemical thermodynamics. Recently a new edition of the reference book appeared (Thermal Constants of Substances: Vol. 1-8 / Ed. V.S. Yungman. - NY: Wiley, 1999). The reference book presents values of the thermal constants for 26976 substances. The list of references contains more than 51500 entries. 
Development of the information system is aimed to solve the following problems
·	to make the important chemical information available for a wide number of researchers all over the world;
·	to make it possible data editing in the reference book or enter the new data;
·	to provide possibility of a quick search of a substance or a group of substances according to some criteria;
·	to provide easy access to the data in the reference book for various specialized programs and ensure the data exchange among chemistry-oriented databases;
·	to enhance the quality of distant education by providing a unique data on thermal constants of substances.
