Beverly Hofstadter has written a number of psychology books, quite a few on Leonard. They are available to purchase on amazon.com.
She has written a book, which we have yet to find out its name, unnamed book, with "there's no guarantee even if you have kids that you're going to like them" right on its cover.
She has written a book entitled "Needy Baby, Greedy Baby" about Leonard.
As of the end of season 9 she was planning to writing a book on overarchiving couples and wants to interview Amy/Sheldon and the Wolowitzes, but not Leonard/Penny. Although, would she do it after when it is the last straw for Penny who has tried to connect with Beverly and now gets angry at her and yells at her for being an insult all day until Beverly admits that she had trouble getting along with Penny because of her marrying Leonard and not inviting her or even telling her the wedding was taking place and after Penny suggests a wedding redo which Beverly finds perfectly acceptable? And the two ladies bond and Beverly being wrong about thinking that Leonard and Penny marrying was a mistake since she had never seen Leonard so happy, showing that she could interview her too now. But nothing for Raj since there was no mention of him in this.
