The absolute best way to search for journal articles is to use a journal article database. These are huge databases of journal articles in various disciplines. Engineering Village 2: Compendex & Inspec are the premier journal article databases for computer science. Journal article databases may also contain information on conference proceedings, patents, book chapters, and book reviews.
Use the Databases link to learn more about specific databases that are useful to you. Some databases have tutorials available. The most difficult part is finding the right database and getting the right keywords. If you don't find something in 15 minutes, switch to another database. Better yet, contact me!
