The Baby-Sitters Club books by Ann M. Martin have been adored by generations of kids since the publication of the first book in the series, Kristy’s Big Day, over 30 years ago in 1986. Just writing that makes me feel very old. As a kid I loved going to the local library every week to stock up on new books, especially during the summers when, at least in my small town, there wasn’t much else to do but read (plus reading outside in the summer is the best).
Over 200 books were published in the series from 1986 to 2000, some written entirely by Martin and others with assistance from ghostwriters, though Martin still provided the outlines and edited the books. Over 176 million copies of the books have been sold worldwide. Much of the inspiration for the stories and characters came from the author’s own life, including years of babysitting in her youth and working as a teacher as an adult.
In the 1990s there was a Baby-Sitters Club TV show and a movie. The books were so popular, there even was a BSC board game (and yes, my sister and I used to play it, although I didn’t like it as much as the Sweet Valley High board game). You can find the game on Amazon and eBay.
