NOT Narrow search, and retrieve records that do not contain the term following it. The format used for authors' names varies from record to record. To narrow the search, add initials or first or other names, e.g. Smith, J . For co-authors it is usually sufficient to use just the last names, e.g jones AND smith . Acronyms Include in your criteria the terms spelled out in full as well as the acronym, e.g. UCLA OR University California Los Angeles .
Many records contain abbreviated versions of source journal titles.
