Most libraries have an easy submission form online at their website. Or just pick up the phone and ask for a librarian.
I won't tell you what book you would ask for, but I will just add that if you go to Amazon you'll see my marvelous reviews for HOLLYWOOD SINNERS. Don't you think more people need to read novels about poor people trying to make themselves into stars in 1930s Hollywood? I do. Every library should have a whole section called "1930s Hollywood" with a few copies of my book laying around to get people's curiosity going (and maybe Day of the Locust, too, just because it's old - but my book is so much better).
