I highly recommend reading the following post from the University of Manchester Library’s blog. I get asked this question as well.
Browse The University of Manchester Library website and you will find a large number of business databases. Researchers have to chose which of these is best for their research and this can be influenced by various factors. To guide this decision it is important to remember the factors that lead to academic libraries having many business databases.
The best known business databases are commercial products: for example, Bloomberg Professional, Datastream (Thomson Reuters), and Capital IQ (Standard & Poor’s) . They are available to universities for non-commercial use but their main market is finance professionals. These systems are similar but not equivalent. The companies developing these systems are constantly trying to improve them to maintain or increase their market share, and often this includes providing data that is not available from competitors.
