Databases are the first place to look for articles. Databases usually have information about an article (such as the title, author, name of the journal or magazine in which the article appeared) and they may also contain a summary (abstract) of the article.
Some databases have a complete copy of the articles (called full text). In this case there is a link to an HTML or PDF document.
If you don't see the link below and know the title of your journal, check the journal list here!
