WRDS is a comprehensive Internet-based data management system that allows researchers to easily retrieve information from a wide variety of financial, economic, and marketing data sources. The WRDS component databases are listed below:

COMPUSTAT: The database of U.S. and Canadian fundamental and market information on active and inactive publicly held companies. It provides more than 300 annual and 100 quarterly Income Statement, Balance Sheet, Statement of Cash Flows, and supplemental data items.

CRSP: The Center for Research in Security Prices (CRSP) maintains the most comprehensive collection of security price, return, and volume data for the NYSE, AMEX and NASDAQ stock markets.
