shelff – PDF Book Reader
Organize owned PDF books using folders, metadata files and an annotation-capable reader.
Useful for people wanting file-based library portability
JSON metadata beside PDFs and incremental annotations expose where data lives.
Keep in mind: DRM-free PDFs only as described; encrypted-file support is not password removal and full-text search needs text/OCR layers. Test backups before external agent changes.
