If you need recent articles, begin in MAGS . You can ask a librarian or check CD-ROMS at the UCB Libraries page. The tools for finding journal and newspaper articles are called Periodical Indexes .
Some periodical indexes are general in scope, while others are very focussed on a particular topic.
No index can tell you about all of the articles owned by the UCB Library. Most indexes cannot tell you the UCB call number for an item. They come in many different formats. The type of periodical index you need depends on what you're looking for. Below are links to sites tha t will tell you how to search individual databases.
