Try the library's article discovery tool, ArticlesPlus. ArticlesPlus allows searching across thousands of publishers and millions of documents. As part of your search, you can limit your results to articles from scholarly journals, from newspapers, or to articles that are available fulltext.
To use ArticlesPlus, simply go to the MLibrary gateway page, click on the ArticlesPlus tab over the Search box, enter your search terms and click "go." This search feature is available also at the AAEL page: http://www.lib.umich.edu/aael/
Things to remember:
ArticlesPlus is a very good way to start researching a particular topic.
ArticlesPlus is great for multi-disciplinary and inter-disciplinary research.
Use the filtering options to narrow your results.
ArticlesPlus does not replace subject specific databases for specialized searching, so don't forget about the Avery Index, JSTOR, PAIS, ScienceDirect, or any of those other standards you've become accustomed to using.
ArticlesPlus is not a book catalog (though you will find some books, particularly e-books, in your search results); if you want books in the library, search in Mirlyn.
Google Scholar provides an alternative for finding scholarly articles. If you're searching Google Scholar from on campus or via the library's proxy server you will be able to link through to online articles.
Google Scholar, like ArticlesPlus, is great for searching many sources across many disciplines. It's worth searching with both tools -- there will be some duplication of results, but you'll also find different articles with each tool. Using quotes to make phrases often helps narrow your search results.
Once you have narrowed your searching and focused on a particular issue, you may find that it is valuable to search a more specialized database. For instance, if you are focusing on a transportation issue, you will want to search TRID, a database for transportation research. To find specialized databases, browse the subject lists within SearchTools.
