There are many databases and data sources produced by many different organizations or companies, but this section covers only what the Library of Congress subscribes to and a few other things to aid in discovery. Some are very industry-focused while others that contain articles can be used for industry research but aren't specific to any industry or group of industries. The subscription resources marked with a padlock are available to researchers on-site at the Library of Congress. If you are unable to visit the Library, you may be able to access these resources through your local public or academic library.
