The spinning jenny is a multi- spindle spinning frame, and was one of the key developments in the industrialization of weaving during the early Industrial Revolution. It was invented in 1764 by James Hargreaves in Stanhill, Oswaldtwistle, Lancashire in England. The device reduced the amount of work needed to produce yarn, with a worker able to work eight or more spools at once. This grew to 120 as technology advanced.
Spinning Jenny, a literary magazine founded in 1995-96, primarily publishes poetry. Published annually by Black Dress Press, an independent press in New York City, the magazine is edited by founder C.E. Harrison and designed by Adam B. Bohannon. Distributed to the trade by Ubiquity Distributors, Spinning Jenny belongs to the Council of Literary Magazines and Presses and has received funding from the New York State Council on the Arts.
