If you need to find articles on a TOPIC or SUBJECT, use one of our databases. Databases collect article references from many sources so you can search broadly.
If you have a reference and you want to FIND AN EXACT ARTICLE, use the A-to-Z journal list. Search for the journal title and follow the links to the full text.
Alternately, you can use Google Scholar, which is pretty good at locating EXACT article titles.
There are other databases that use structure search, but SciFinder and Reaxys link the structure search to the chemical literature.
Use encyclopedias and other general references to get a topical overview before diving into the specific journal literature. Ullmann's and Kirk-Othmer both offer substantial non-engineering content.
