Search Hints:

• Use "and" to combine words to define search criteria (eg., bivalve and copper- this example will find documents that contain both words.)
• use quotes (" ") around "text strings" to find exact phrases (eg., "reference envelope approach" - if you type in reference envelope approach with out the quotes, it will find all documents that contained the words "reference" or "envelope" or "approach", not "reference envelope approach."
• If the search returns "hits," use your browser's "Find" or "Search" function (usually "Ctrl+F") to locate the search term within the document.
