In addition to to being a great source of national and international mainstream news, Google News also has a great collection of historical news articles (and in some cases scanned newspapers). It also has a great feature called Google Alerts where you can set up an email alert any time a particular company, individual or topic that gets posted on a blog, in a newspaper or on the Internet.
In the age of the Internet, an often forgotten source of information is current and historical books.

While a lot of news aggregation websites such as Lexis Nexis, Factiva and the aforementioned Google News have information from mainstream news media, sometimes the best information can be found in the local small town newspapers. Many of these sites allow you to search current and recent articles for free but most of these sites require a fee to retrieve historical information.

FINRA provides a array of information regarding a persons work history, qualifications and any disciplinary/regulatory issues. FINRA currently only has information who have been actively registered over the last two years; anything beyond that, you would have to contact your local state securities regulator.
