Many, if not most, of the databases you'll search for this project share tools. Here are some of them.
Publication date - limit your search to a particular date range
"Relevance" - this option usually brings up a pulldown menu that will give you the option to sort your search results by publication date ("newest first" - the most recently published will show up first in the list of results; "oldest first" - the oldest article will show up first)
Full text - your search will be limited to only those articles that appear full-text in the database. NOT a good idea. Use "UC e-links" to find the full text of articles in other databases.
