By narrowing a search you need to think about your general topic - The National Football League - and think in terms of some aspect of that topic you would wish to investigate. In your question you have already begun to narrow, by focusing on the history of the NFL organization.
One way you can further narrow your focus is by looking at how that subject is written about. My first suggestion would be to look in the book catalog (on the library webpage, left side) and type in national football leagaue. You will see a book listed that discusses the development and growth of the league. The title is America's Game, and the call number (location) of the book is GV954.M32 2004. If you are able to look through the table of contents you will see how the topic can be broken down into smaller more manageable research topics.
The next step would be to try one of our electronic databases, such as Academic OneFile (link below). Using the SUBJECT GUIDE SEARCH on the top of the search page, and enter National Football League. Your results will have a link to SUBDIVISIONS. When you click on this, you will see the subject of the National Football League broken in its various, narrower, elements. You can click on History if that is still your focus and you will have many choices of articles. Looking through the titles of some of these will help you further refine, or narrow, your topic.
