They will get into more detail than you can handle, and they will not be very current. So
Internet-based research is fine.
As always, when you use internet sources, make sure to consider how reliable they are or what their biases are. Don’t believe it if the national newspaper of Venezuela tells you that rumors of hyperinflation are fake. If you can’t figure out who runs a website or published an article, be skeptical. And don’t cite Wikipedia. You can look at it to get a background or to get directed to other sources, but it is not a citable source.
For example, here’s what I would do if I were working on Albania. I googled “Albania country report” and found these very quickly, all of which would be useful:
US Investment Climate Reports
CIA World Factbook (Economy summary)
IMF Country Report
The Economist Intelligence Unit Country Report
Googled: Albania macroeconomy
Discussion of conditions for joining EU.
Google news: Albania currency
