 Intertitles are lacking in some LC Biograph elements (not to be confused with Biograph films originally released without intertitles). Elements lacking intertitles are found in both the Paper Print and Pickford Collections. In the early 1920's, producer Nathan Hirsh added new intertitles to reissue versions of several Pickford Biograph titles. Material with Nathan Hirsh reissue intertitles are documented in the notes field for each element.
