Married Love or Love in Marriage is a book by British academic Marie Stopes, first published in March 1918 by a small publisher, after many other larger publishers turned her down because of its controversial content. It rapidly sold out, and was in its sixth printing within a fortnight. The US Customs Service banned the book as obscene until April 6, 1931, when Judge John M. Woolsey overturned that decision. Woolsey was the same judge who in 1933 would lift the ban on James Joyce's Ulysses, allowing for its publication and circulation in the United States of America.
