Bronte Society hopes to return a rare early book written by one of the famous literary sisters to Britain when it is later auctioned in Paris.
The work is one of six "small books" written by Charlotte, the eldest of three sisters, in 1830, when she was 14 years old.
The society that runs the Parsonage Museum at its old home in Haworth, West Yorkshire, is trying to raise the £ 650,000 it needs.
The miniature is in private hands since the death of Brontes.
The tiny book, which contains three handwritten stories, is one of six written by Charlotte, of which five survived. The Bronte Parsonage Museum already has the other four.
The works, called The Young Men & # 39; s Magazine, were created for the Charlotte soldiers and document the imaginary world created by the Glass Town family.
Charlotte is best known for her 1847 classic novel by Jane Eyre.
The existence of a book put up for sale – 35 mm x 61 mm and consisting of 20 pages – was revealed in 2011, when it was put up for auction at the Sotheby's store.
Bronte's society broke through the discredited investment program, which is no longer working.
Kitty Wright of Bronte Society said: "This amazing manuscript slipped through our fingers in 2011, so we're particularly determined to make the most of the second opportunity to bring him to Haworth."
Rebecca Yorke, also from society, said more than 900 people promised money to buy the book.
"They also expressed how strongly they feel that it remains in Haworth, where visitors and researchers can enjoy them," she told BBC Radio 4 Today.
Several celebrities, including Dame Judi Dench, Dame Jacqueline Wilson and Tracy Chevalier, supported society's efforts to raise money.
York-born Dame Judi, who is president of the Bronte Society, said earlier this year: "I have long been fascinated by small books created by Brontes when they were children.
"These little manuscripts are like a magical entry into the imaginary worlds in which they lived, and also indicate their ambition to become authors."
The catalog of the auction house in Paris says: "This is a unique opportunity to get such a valuable autograph from a brilliant novelist, as well as take a look at children's games and the imaginary world of Bronte's" Glass Town "."
Part of a magazine for young men describes a murderer driven mad after his victims haunt him, and how a "huge fire" burning in his head lights up curtains.
Museum experts say this part of history is the "clear precursor" of the famous scene between Bertha and Edward Rochester in Jane Eyre, which Charlotte will publish 17 years later.
