Abstract
Major libraries have large collections and circulation. Managing libraries electronically has resulted in the creation and management of large library databases. The interconnection of libraries and sharing resources across libraries has resulted in the management of very large databases. Most large and/or multinational industries worldwide have exploited such opportunities by applying data warehouse technology to their data repositories to discover knowledge that had helped them to gain competitive advantage through decision making. The same can be done for libraries using the available large databases. This paper identifies the changes that had taken placed in libraries due to technology and how the data warehouse technology could assist them to discover knowledge and improve services.

Highlights
A library would record data about their books using library catalogues
In a manual library system one maintains library catalogues only in author sequence as each catalogue entry requires a separate entry card which is placed in the catalogue drawer
A Decision Support System (DSS) is any tool used to improve the process of decision making in complex systems
Summary
A library would record data about their books using library catalogues. Each catalogue consists of data about the author, title, subject, publisher, edition, place, year, language and ISBN of the book. Digital libraries allow easy of reaching information through search engines and indexing techniques It has provided solutions for other issues such as space, preservation of books and rescuing the content of fragile material. Users can use data mining techniques on the data warehouse to extract different kinds of information which would eventually assist the decision making process of an organisation (figure 1). If certain books are rarely used by members of a particular library, while the same books are frequently used at other libraries it is appropriate to transfer these books to respective libraries to ensure its effective use Such knowledge could only be discovered through sharing experiences of librarians or by capturing the knowledge through database and integrating them as done when building data warehouses.
