The LdoD Archive is a collaborative digital archive of the Book of Disquiet by Fernando Pessoa. It contains images of the autograph documents, new transcriptions of those documents and also transcriptions of four editions of the work. In addition to reading and comparing transcriptions, the LdoD Archive enables users to collaborate in creating virtual editions of the Book of Disquiet. It also includes a writing module which, in the future, will allow users to write variations based on fragments from the Book. The project started in 2012 and its first release was published in December 2017.
