I enjoy the website Awful Library Books. "This site is a collection of public library holdings that we find amusing and maybe questionable for public libraries trying to maintain a current and relevant collection. Contained in this site are actual library holdings." Librarians post about books they are weeding out of the library. Many are old and no longer relevant - and hysterical.
Given I work in romance publishing, I was, umm, entranced by the 1984 Romance Writers' Phrase Book by Jean Kent and Candace Shelton. Yep, over 3000 phrases you can use to enliven your romance writing and bring variety to your prose. The section on sex scenes includes such unusually creative suggestions as:
his glance slid rapidly to her bathing suit and his mouth softenedAnd for a really super-graphic sex scene in 1984:
she noticed he was watching her intently
his gaze traveled over her face and searched her eyes
there was a tingling in the pit of her stomach
he was as eager and erratic as a summer storm
her body ached for his touch
she was powerless to resist
she was pleased with their initial intimacy (Oh, boy, doesn't that just turn you on!)
You can find many other helpful suggestions in the book pages displayed.
At the end of the post, it mentioned the book was for sale on eBay. Don't bother trying for it - I rushed right over and bought it. I must have this for my collection!
