This paper describes the implementation of World-Wide Web (WWW) access of the SEC EDGAR (Electronic Data Gathering, Archiving and Retrieval) data base. EDGAR is a large, heterogeneous financial data archive that has been available to Internet users since January 1994. It is composed of all forms filed electronically to the Securities and Exchange Commission (SEC) by domestic publicly traded corporations and mutualfunds. We describe WWW design decisions and problems encountered in implementing a public access system to a large database. Our current applications include: an object-oriented mutual fund equity holdings database, a structured full text index search oncorporate profiles, and real-time graphical visualization of stock price and mutual fund position changes.
