In a nutshell:
* Dickinson’s poems are discovered after her death, and sister Lavinia enlisted the help of her sister-in-law Susan to get them published.
* Unhappy with the slow pace, Lavinia turned to her brother’s mistress, Mabel Loomis Todd (LOL – just like the youth of today, she was proficient with the use of the day’s new technology – the typewriter).
* As a result, Dickisnon’s poetry was spread among three households: some with Lavinia Dickinson, some with Susan Dickinson, and the rest with Mabel Loomis Todd.
* With the help of Dickisnn’s friend Thomas Wentworth HIgginson, Todd published the first edition of Dickinson’s poetry in 1890.
* The second and third editions were published in 1891 and 1896. Todd also published an edition of Dickinson’s letters in 1894.
* However, all efforts to publish more of Dickinson’s poetry came to a halt in 1898 due to a “painful” lawsuit between Lavinia Dickinson and Mabel Loomis Todd. The suit was not over the poetry, though; it was all about a small parcel of land Austin Dickinson (who had died in 1895) had promised to Mabel Todd and her husband.
* Angered by the fact that Lavinia Dickinson won the lawsuit, Mabel Loomis Todd locked all of the remaining poetry she had in her possession in a chest – and it wasn’t opened for more than forty years.
* In the meantime, between 1914 and 1935, other volumes of Dickinson’s poetry were published by Emily’s niece, Martha Dickinson Bianchi and Alfred Leete Hampson (and just as an FYI: I need to research more about Hampson because I’m not sure who he was exactly – although I know that upon Martha Dickinson Bianchi's death in 1943, the Hampsons inherited Susan and Austin Dickinson's house, the Evergreens).
* In the meantime, Mabel Loomis Todd and her daughter Millicent Todd Bingham unlocked that chest of poetry, and they worked on a volume entitled “Bolts of Melody” which included 600 previously unpublished poems. Mabel died in 1932, but daughter Millicent saw the project through, and the volume was published in 1945 – under both names: Mabel Loomis Todd and Millicent Todd Bingham.
