Should I include my personal development library in my resume?

I have some college and no degree. Would it be helpful or harmful to put the authors and titles of the relevant books I’ve in my resume?

Probably not useful.

If you’re talking about books you’ve read to develop skills, list the skills you’ve developed without listing the book. If you’re talking about books like Seven Habits of Highly Effective People, or Five Disfunctions of a Team, they don’t belong on a resume. You can discuss their influence on you in a cover letter, if appropriate.

If your college courses focused on a specific area, you can mention that area after you list the school you attended.
