Question

when referring to the title of a book in a paper, using apa style, is the title underlined?

Answer 1

Titles of books are capitalized according to "sentence structure" capitalization ex. first word of the title, all proper nouns and the first word after the colon if there is a subtitle.

Answer 2

Author, A. A. (Year of publication). Title of work: Capital letter also for subtitle. Location: Publisher.
From our Purdue partner site, OWL
Example: Plath, S. (2000). The unabridged journals. K.V. Kukil, (Ed.). New York, NY: Anchor.

I don't see underlining of the title, its italicized.

Answer 3

OK, italics not showing on my post, the Title needs to be italicized.
Example: Duncan, G. J., & Brooks-Gunn, J. (Eds.). (1997). Consequences of growing up poor. New York, NY: Russell Sage Foundation.
Consequences of growing up poor: Title needs to be italicized.

Answer 4

A lot of these answers are wrong--they point to MLA style, not APA. Look at a copy of the APA style guide. The Purdue OWL has a short version: owl.english.purdue.edu
