It's possible to go scouting for data to see what you can find.
One method is to go to the research database called Academic Search Premier [see below for link], and try some searches for lists.
Example 1.
- search for: list AND 500
- The idea is to see if you can find an article about a list (of anything) that has 500 items, such as the "Fortune 500" companies.
- With the above search, I found a Green List 500 of companies provided by Newsweek. To see the list and variables associated with it,
- search Google for: newsweek "green list" 500
Example 2.
- search for: list AND best
- the idea is to get lists of the best (of anything).
- With the search I found a list of the best public golf courses in all 50 states.
- When I looked over the list, it had over 300 golf courses. However, no associated variables were provided.
- To gather variables, I would need to google each golf course individually or search the library catalog for a golf course directory with more detail or search google for a source of details about individual golf course. In google, I might try a search for : golf courses united states [and then hunt in the results for directories or other sites that compile information on lots of golf courses]
