If your word processor cannot support this type of formatting, then use an underscore to indicate that the title should be underlined.

Add the name of the publishing company and a final comma. This information will often be located on the inside cover or on the back of the book. If your book was published by Letterman's Friends in Denver, Colorado, then at this point your citation should look like this:Lawrence, M. (ed.) 1976, _Gnostic Thoughts on Shakespeare_, Letterman's Friends,
Finish with the city where the book was published and a period. It is not necessary to include the state or country. Your finished citation should look like this:Lawrence, M. (ed.) 1976, _Gnostic Thoughts on Shakespeare_, Letterman's Friends, Denver.
