Recent strategies for retrieving chemical structure information on the Web

Abstract
Discusses various structural searching methods available on the Web. some databases such as the Brookhaven Protein Database use keyword searching which does not provide the desired substructure search capabilities. Others like CS ChemFinder and MDL's Chemscape use graphical plug in programs. Although plug in programs provide more capabilities, users first have to obtain a copy of the programs. Due to this limitation, Tripo's WebSketch and ACD Interactive Lab adopt a different approach. Using JAVA applets, users create and display a structure query of the molecule on the web page without using other software. The new technique is likely to extend itself to other electronic publications
