Surfing the Organic Chemistry Hyperdocument with CrossFire plus Reactions1

The CrossFire system has been extended to permit reaction substructure searching and to give increased performance and access to the Beilstein database. The system is now comprised of three superdocuments:  substances (structures and properties), reactions, and citations. These together form the organic chemistry hyperdocument, where the individual documents are hyperlinked to each other. This construction allows the user easy navigation through the organic chemistry hyperdocument by means of data surfing. An example of a reaction substructure search applicable to combinatorial chemistry is shown.
