Please note: The typed transcripts of Ackley's letters in this book were the first attempts by the Adams family to explicate them. The transcripts attempt to be exact verbatim, retaining Ackley's variable spelling and punctuation. Spelling and punctuation were normalized for easier reading in the Word and Word Perfect versions on the CD and in the final, printed manuscripts. The numbers given each letter in this book (upper right hand corner of the plastic sheet folder) do not correspond precisely with final numbers assigned to the printed transcripts. Some letters not available at the time the typed transcripts were made were added later, and the sequence adjusted accordingly.
