The Al and Ruth Kopolow (Business) Library supports the business information needs of those in the Business School and the general university community. When possible, we also assist individuals and business patrons 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, ThomsonOne, Morningstar, IBISWorld, and others.
