Chemists have been very active in utilizing the World Wide Web as an information distribution medium and much interesting scientific chemical information is already offered on it. Various classical text-based search engines have made locating information on the Web easier. However, keyword-based searches are often insufficient for chemists interested in structural features of chemical compounds, especially since the naming of chemical structures is far from simple or unique. Chemists have special search requirements and rely on non-textual structure-oriented search methodology. An increasing number of chemical structures can be found in various computer-readable structure exchange formats as MIME attachments to Web pages on the Internet. If they are cataloged and made searchable with the structure-oriented search methodology that chemists are used to, they can lead to valuable chemical information sources on the Internet which are difficult to locate with other, text-oriented search methods. The Computer Chemistry Centre, University of Erlangen-Nurnberg, (Germany) has implemented a system for the collection, recording, search and context-aware retrieval of chemical structures from the Web.
