Because it is hard for an individual to compile large amounts of data, many people will contact an information bureau in order to gain access to certain types of information. There are many different government information bureaus that provide resources for the public, free of charge, such as the better business bureau, the census bureau and city and state information bureaus. There are also private information bureaus that, for a fee, can allow people to access hard to find information such as personalized credit reports. Information bureaus are often a powerful tool for accessing and understanding large amounts of data.
