This paper presents an image–annotation dataset of student movement and related social movement materials held by the Tohoku University Archives. Version 1.1.0 contains 690 distributed JPEG and TIFF images derived from 676 pre-split images and 690 corresponding UTF-8 JSON files, with 5,781 block annotations and 47,631 line annotations. The records include bounding boxes, manual transcriptions, writing direction, and printed/handwritten classifications. Two JSON implementations created under a shared functional specification are preserved. The dataset supports OCR/HTR, layout analysis, page-text reconstruction, document-image understanding, and search-oriented evaluation.
