Please give me Tomboys, LC

While cataloging The Pac-Man Fever zine I discovered that there is no Library of Congress Subject Heading or even cross-reference for Tomboys. That's disappointing.

I did a keyword relevance search for tomboys in the Columbia Libraries catalog and found these helpful headings (among others):

• Aggressiveness in children
• Gender identity
• Gender identity disorders in children
• Girls --Psychology
• Girls --Sexual behavior
• Sex role in children

Which one is your favorite?

I would also have liked to apply Butch lesbians as a subject heading.
