Where can I go to find out about the infrastructure (shipping, roads, airports, etc) in Bhutan?
I suggest you start with our Business Cornerstone Research Guide. To get there select RESEARCH GUIDES tab from the library homepage https://www.uhd.edu/library/Pages/library-index.aspx . Then choose the Class Guides link and then the link for BA 3300 - Business Cornerstone. Once in the Business Cornerstone guide, go to the Country Resources tab. (Here's a quick link http://library.uhd.edu/content.php?pid=113723&sid=984047)
In the Demographic Information box, choose the CIA World Factbook link. Once in the CIA World Factbook, select Bhutan from the drop down menu. Scroll down and click on the pink Transportation bar. This will give you some statistical data on airports and roadways.
The other country databases listed with CIA World Factbook do not have much information on Bhutan infrastructure. To get more information, I think you'll need to search for articles in our business databases. Back in the Business Cornerstorn Research Guide, choose the General Business Resources tab. The first database, ABI/INFORM Complete, seems to have the most information on your topic.
In ABI/INFORM, try these searches:
Bhutan AND infrastructure
Bhutan AND transportation
I suggest you check "Full text" under the search box, and you may also want to check "Peer reviewed" if you need scholarly, academic articles.
