You can search the catalog for books and journals at the same time. If the library doesn't have what you want, you can order it via ILL.
1. Select Advanced Search from the main menu. You have more control over your search with Advanced Search.
2. Your next step is to Sign In. This way the system knows you and helps to check out material, you can order works we don't have via ILL, etc. The Sign In button is on the far top right. Enter your Banner ID and password.
3. From the Advanced Search screen, type in your search terms. You are casting a wide net, looking for results but can filter and sort through the results.
In the above example, I searched Everything, chose Any Field, and typed in my search terms.
4. Note on the left side of the screen that you can expand, sort, and filter your results in various ways.
1. Expand your search to search for books and articles NMSU does not own. This is helpful if you are not finding much on your topic and you are certain of your subject terms.
2. You can Sort your Results List in various ways, most recent, relevant, etc.
3. You can filter your results in a variety of ways too. But, be careful! don't restrict your search at the outset to only materials available online, or only peer-reviewed because you could be excluding important works.
4 and 5. You can also filter your results by type: book, journal article, etc. or by location, publication date, language, subject, etc. You can even filter by video.
5. Here's a book entry.
On the right you have choices of various tools: email, permalink (URL), add item to a folder, citation (click on the ...)
And below the entry, you see the location of the book (Zuhl) and the call number. This book is also available as an e-book.
6. When you click on the full record entry, you find other helpful information.
7. And here is an entry for a peer-reviewed journal article. 
There's a new productivity tool on the top right. The red merging down arrow allows you to search for articles the author has cited. The reverse red merging up arrow (found in other article entries) allows you to search for articles that have cited that journal article. Very helpful!
You also have a brief article citation, a quote from the article, the peer-reviewed symbol and notification that the article is available online.
8. With the full entry for this article, you have a healthy list of other subjects you could add to your search vocabulary.
9. Let's say you are not finding much, have expanded your search (see #4 above), and you have found the relevant articles or books. What then?

And once logged into ILL, citation information instantly populates the data fields.
Here are several databases I recommend for your project. These are in A-Z order and not in order by my preference. All your topics are different so you will need to use different databases.
Read the descriptions and decide which are best for you. If you have already searched the catalog for articles, there will probably be some overlap.
Some of these databases are full-text, they are not limited to journal articles only (Border and Migration Studies Online, History Reference Center include reports, videos, reference works, books, etc.) and one is a video database with a focus on documentaries (Academic Video Online). This last database includes transcripts and ways to cite the videos.
