Perhaps as early as 1787, Austen began to write poems, stories and plays for her own and her family's amusement. Austen later compiled "fair copies" of these early works into three bound notebooks, now referred to as the "Juvenilia," containing pieces originally written between 1787 and 1793. (from Wikipedia)
.
The 1st volume of juvenilia includes:
* Frederic & Elfrida
* Jack & Alice
* Edgar & Emma
* Henry and Eliza
* The Adventures of Mr. Harley
* Sir William Mountague
* Memoirs of Mr. Clifford
* The Beautifull Cassandra
* Amelia Webster
* The Visit
* The Mystery
* The Three Sisters
* Detached Pieces (A Fragment, A beautiful description, The generous Curate, Ode to Pity)
