After you have picked a database, choose the type of search you want to perform. You can search on title words, subject words, and authors. The fourth option is the most flexible type of search - the Power search. You can opt to enter any words in the title or the complete title. Truncation can be used only at the end of a word.
Author Enter only one author name per line.
There is an additional line to enter a second author. Use this if the first author has a common name. Enter last name first and separate the first name from the second by a comma. Consider truncating first names. Others use both first initials and full names.
