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.
Citation managers (like Mendeley) allow you to save your references and drop them into papers or bibliographies in the format of your choice. Mendeley and Zotero are installed on computers at the Science and Technology Library.
Probably not unless you plan on publishing your work publically (thesis or dissertation, journal article, etc). If you want to reuse images/figures from another author in your published work use the Copyright Clearance Center to find permission rules for various publishers.
You can also email the librarian for more help.
