Information and documentation - Object preserving digitization of archive and library material
1Key Takeaways
Scope: This standard specifies requirements for the object-preserving digitization of archive and library materials. It covers project planning, preparation, scanning procedures, post-processing, and quality assurance measures to ensure the preservation of original documents during digitization. The standard applies to…
2Expert Interpretation
Professional interpretation of the German DIN 33910:2023-08 standard, covering the technical specifications and cultural relic protection requirements for the entire process of digitization of archives and library materials, including core content such as project planning, scanning equipment selection, and cultural relic transportation and storage, to help cultural heritage institutions achieve high-quality digitization.
Standard Overview and Background
DIN 33910:2023-08 is a special standard for lossless digitization developed by the German Institute for Standardization for archival and library materials. This standard replaces the earlier version and mainly responds to three core needs in the field of digital cultural heritage protection:
- Solve the differentiated processing requirements of mixed-carrier cultural relics (such as parchment, bound documents, and loose-leaf materials)
- Establish a collaborative framework for preventive protection and digitization technology
- Standardize quality control nodes in outsourced services
Analysis of core requirements
| Process stages | Key technical indicators | Cultural relics protection measures |
|---|---|---|
| Preliminary preparations | Status record completeness ≥95% | Mandatory requirements for microbial contamination detection |
| Transportation and storage | Temperature and humidity fluctuations ±1℃/±3%RH | Multi-layer cushioning packaging system |
| Scanning process | Complies with ISO 19264-1 imaging standard | Maximum opening and closing angle control |
Key technical specifications
5.4 Pre-processing requirements
The standard clearly states that fragile documents must complete the following pre-processing before digitization:
- Use acid-free materials to fix loose pages
- Remove metal parts that may cause mechanical damage (staples, etc.)
- Professionally flatten warped documents
7.2 Scanning equipment selection
Configure dedicated equipment according to the type of document:
Case Study: 18th-century parchment-bound books require a V-shaped book rest scanning system, combined with cold light source illumination, with the opening and closing angle controlled within the range of 90-120°.
Implementation Suggestions
Project Management
It is recommended to adopt a three-stage quality control:
- Pre-processing stage: signature confirmation by the cultural relic restorer
- Digitalization process: 10% sampling inspection of each batch
- Post-acceptance inspection: item-by-item comparison with the original
Staff Training
The standard requires that scanners receive refresher training on cultural relic handling every three months, with key points including:
- Identification of ancient book binding structure
- Use of special tools for fragile carriers (such as acrylic page turners)
- Emergency handling process
