Deciding whether or not to transcribe the family letters and the parent notes is an agency decision. If this transcription is being done for the publisher or to be put in a general library, everything on the page should be transcribed. On the other hand, if it is for one client, it depends. If the transcription is being done for the child, you may choose to omit the text that is meant for the adult. If the transcription is being done for the parent, then the notes and letters should be included. Check with the requestor to see what is needed. If the book is being prepared for general use and not for a specific client, then you might consider putting the family letters and the parent notes at the end of the chapter. This transposition or omission must be stated on the transcriber's notes page.
