Little Women is a novel by American author Louisa May Alcott, which was originally published in two volumes in 1868 and 1869. Alcott wrote the books rapidly over several months at the request of her publisher. The novel follows the lives of four sisters—Meg, Jo, Beth, and Amy March—detailing their passage from childhood to womanhood, and is loosely based on the author and her three sisters. Little Women "has been read as a romance or as a quest, or both. It has been read as a family drama that validates virtue over wealth", but also "as a means of escaping that life by women who knew its gender constraints only too well". 6 : 34 According to Sarah Elbert, Alcott created a new form of literature, one that took elements from Romantic childrens fiction and combined it with others from sentimental novels, resulting in a totally new format. Elbert argued that within Little Women can be found the first vision of the "All-American girl" and that her multiple aspects are embodied in the differing March sisters. The book has been adapted for film twice as silent films, and four times with sound, in 1933, 1949, 1978 and 1994. Four television series were made, including two in Britain in the 1950s and two anime series in Japan in the 1980s. A musical version opened on Broadway in 2005. An American opera version in 1998 has been performed internationally and filmed for broadcast on US television in 2001.
