For most lower level, non-professional research, a general database will cover most of what you need, including the basics of a topic and the latest developments.
For more scholarly, upper level research, you will want to use our subject specific databases. Try searching in a database that covers only the fields you're interested in. Many physics-related databases can be found in the following section.
Many of our physics journals are indexed by their publisher. Begin with these databases for full text articles.
Please use the Journal Locator to see if your article is available. Any article not immediately available can be requested via ILLIAD.
