So what are "traditional" information resources?

When I talk about "traditional" sources for business research, I include the paper-based resources that we've had for centuries, as well as the established, online tools that provide verified and relatively reliable information:

Tax records
Government documents
Required business filings
Patent databases
Business databases

"Traditional" sources provide information that is the basis of competitive analysis:
financial statements, credit ratings,
news articles from major media outlets.

What types of business research can you find in "traditional" information sources?
