A single-page colour-coded tracking chart of the Shuttle-Craft Bulletin, listing each volume from 1924 (v01) to 1964 (v41) by month or issue number. It shows which issues were not issued, which exist, and which were marked done or finished, apparently for a digitization or transcription project. Early volumes are numbered consecutively (001-067), later ones are listed by month, and some later volumes use P-prefixed codes. The chart has no weaving content.
