"Fear of Flying," the landmark work of women's sexual liberation, is officially middle-aged.

The book by Erica Jong, now a Weston resident, is being re-issued in a 40th anniversary edition, and the writer herself will be on hand Wednesday at the Westport Library to talk about changes -- good and bad -- since the novel's publication caused cultural shock waves four decades ago. Since then it has sold more than 20 million copies.

The program starts at 7 p.m., and is planned in conjunction with the annual the Westport Arts Awards Celebration

Jong will be introduced and moderated by journalist Mary-Lou Weisman.

Copies of "Fear of Flying," both paperback and hardcover editions, will be available for purchase and signing. A portion of the proceeds benefit the library.

Jong, the author of 19 books of poetry, fiction and memoir, left a PhD program at Columbia University to write "Fear of Flying," which was published in 1973.

The book "challenged conventional thinking about women, marriage and sexuality and remains a timeless tale of self-discovery, liberation and womanhood," the library said in announcing Jong's appearance.
