Document Digitization in Archives and Libraries: From Preservation to Digital Workflows

Document digitization has become one of the strategic tasks for archives, libraries, documentation centers, and administrative management units. The pressure to preserve fragile collections, improve remote access, streamline internal processes, and ensure digital continuity has made digitization no longer a one-off project, but a core competency for information professionals.

In practice, we work with heterogeneous collections: books and historical newspapers, manuscripts, photographs, maps, administrative documents, and special collections. Each presents different technical and organizational challenges. Added to this is the need to ensure capture quality, properly manage color, record reliable metadata, and plan robust storage systems. All of this requires a deep understanding of technical foundations and the workflows that underpin a digitization project.

This scenario is not exclusive to the heritage sector. E-government, corporate records management, and institutional repositories also depend on well-designed digitization processes. What changes is the purpose: while in a historical archive visual fidelity and long-term preservation are paramount, in an administrative archive the priority may be readability, efficiency, and interoperability with processing systems.

In all cases, digitization is now a cross-cutting competency that combines technology, archival criteria, quality standards, and rigorous planning.

What High-Quality Digitization Involves

Digitizing is not simply “scanning.” A solid project requires understanding the technical elements that determine the quality and usefulness of digital images:

Raster digital imaging technology and digital text. Spatial resolution, bit depth, compression, and output size determine the fidelity of the digital document. Understanding how pixels are represented, how formats behave, and how file size is calculated is essential for informed decision-making.

Color management. This is one of the most overlooked yet most critical aspects. Without ICC profiles, calibration, and color control, the appearance of documents can be severely distorted, especially in photography, illustration, maps, or manuscripts. Color management ensures that what is captured, displayed, and printed remains consistent.

Phases of a digitization project. From awareness and needs assessment to execution, quality control, and maintenance of the digital collection. Each phase involves technical, organizational, and economic decisions that must be documented and justified.

Quality control. This guarantees that the project meets its objectives. It includes equipment evaluation, capture review, error detection, correction, and parameter adjustment. Without a quality system, even a well-planned project can fail.

Metadata. These are essential to contextualize, manage, and preserve digital objects. They include descriptive, technical, provenance, and rights metadata, as well as standards such as EXIF, XMP, MIX, and METS.

Mass storage. The selection of RAID systems, cloud storage, backups, file naming conventions, and folder organization determines the durability and accessibility of the digital collection.

Digitization is, ultimately, a technical process but also a strategic one. It requires sound judgment, planning, and a clear understanding of institutional goals.

Applications in the Professional Environment

The possibilities for application are broad and affect different areas:

Preservation and access to heritage. Digitization helps protect fragile originals and provide remote access to historical collections, facilitating research and cultural dissemination.

E-government and records management. The digitization of files, invoices, contracts, or personnel documentation is key to interoperability, efficiency, and the legal validity of administrative processes.

Digital libraries and repositories. Creating digital collections requires high-quality images, consistent metadata, and standardized workflows.

Research projects and digital humanities. The availability of high-quality images and structured metadata enables advanced analysis, text recognition, annotation, and scientific reuse.

Internal processes and workflow optimization. Digitization facilitates automation, traceability, and process improvement in both public and private organizations.

In all these contexts, technical quality and proper planning determine the success of the project.

A Training Opportunity

For those who wish to acquire a solid and practical foundation in document digitization, SEDIC offers the course “Document Digitization,” taught by Jesús Robledano Arillo, Associate Professor in the Department of Library and Information Science at Universidad Carlos III of Madrid and Director of the Master’s Degree in Libraries, Archives, and Digital Continuity.

Jesús Robledano holds a PhD in Information Science, has been principal investigator in numerous projects on information management and retrieval, digitization, and digital preservation, and has served as Vice President of SEDIC. His career combines university teaching, research, technical consultancy, and participation in digitization and imaging technology projects.

The course, consisting of 45 teaching hours, is delivered online with a strongly practical approach. The program covers:

• Fundamentals of raster digital imaging and digital text

• Color management and ICC profiles

• Phases and planning of a digitization project

• Quality control of equipment, processes, and results

• Technical, structural, and preservation metadata (EXIF, XMP, MIX, METS)

• Mass storage systems and file organization

It includes practical exercises, audiovisual materials, and personalized tutoring. Places are limited.
