The oldest known manuscript of "Dasam Granth" is likely the Anandpuri bir. It is dated to the 1690s, but a few folio pages on Zafarnama and Hikayats were definitely added later, because they are composed after 1700, are in a different style and format, lacking the folio numbers present on all pages elsewhere. These letters of Guru Gobind Singh were likely appended to it in the early 18th century. According to another view, the earliest surviving manuscript of the complete text is dated to 1713, and the early manuscript versions have minor variations.
