Al and Ruth Kopolow (Business) Library

The Al and Ruth Kopolow (Business) Library’s main goal is to support the business information needs of those in the Business School and the general university community. When possible, we also assist individuals and business people outside of the university. Over the past two decades, the business library has evolved from a collection of print books and journals into a database oriented research and service center. The bulk of our information resides in over 55 databases that cover the full range of business information including articles, financial data, market research reports, stock analysis, corporate filings, etc.  The library has online directories of private firms, public corporations, hedge funds, private equity firms, M&A data, and more. Some of our most heavily used databases include Bloomberg, Business Source Complete, Factiva, MarketLine, Thomson One, Morningstar, IBISWorld, and others.

Check out our new Research Guides for business research on companies, industries, international, and finance.
