Zibby wrote a memoir, 40 LOVE, about falling in love again at 40. She was represented by The Bent Agency for that project, but has decided to leave the unpublished manuscript on the shelf. (This was just a proposed cover she had designed.)

She is currently starting over and writing a novel with similar themes.

"What to Wear to Show Off Your Assets. What to Do to Tone Up Your Trouble Spots."

Zibby co-authored this non-fiction, fashion/fitness book with Paige Adams-Geller, founder of Paige Premium Denim, and Ashley Borden, a celebrity trainer. The book was illustrated by Lauren Riback. It was published by McGraw-Hill (January 2008).

Zibby self-published this personal memoir/parenting advice book (November 2009) as a gift for her best, oldest friend, who was pregnant with boy/girl twins.

Zibby wrote OFF BALANCE first as a memoir and then as a novel. It was about a 20-something student at Harvard Business School who loses her best friend on 9/11. It was represented by Sara Crowe at the Harvey Klinger Agency in 2004 but was not accepted for commercial publication. It is also on the shelf.

Zibby edited this book for Karen Bartolomei, a former subject of one of her Elegant Bride profiles, in 2008.

While at Yale, Zibby was co-Editor-in-Chief of The Insider's Guide to the Colleges 1999. She also contributed to the 1996, 1997 and 1998 editions. 

Zibby wrote two short stories when she was in third grade. Her grandfather, Kalman Levitan, a collector and publisher of miniature books (The Kaycee Press), published a limited edition of them as miniature books in December 1985.
