ReferenceUSA, an Infogroup company, has been serving the library community since 1992. Through our easy-to-use online SaaS (software as a service) platform, we provide library patrons access to extremely accurate and complete business and consumer data.\\No other big data provider goes to the lengths we do to ensure the data your patrons rely on is relevant, comprehensive, and up-to-date. We begin by collecting hundreds of thousands of public information sources. From there, our research staff analyzes and verifies every record and compiles all the information into easy-to-use databases.
