The process of converting physical collection items (documents, images, objects, audio, video) into digital surrogates through scanning, photography, or other digital capture methods, producing digital representations intended for access, analysis, or preservation workflows. Digitization outcomes vary by capture quality, metadata, and intended use.

Principle

A digitized surrogate conveys visual, textual or signal representations of an original but is not inherently equivalent to the original's material properties or a substitute for active long‑term preservation unless accompanied by appropriate preservation actions and metadata.

Demonstration

Illustrative scenario — Situation: A fragile bound manuscript is frequently requested for research. Recognition: Handling risk is high. Action: The library captures high‑resolution archival images, attaches descriptive and technical metadata, and publishes lower‑resolution access copies. Consequence: Researchers access the content remotely, handling of the original decreases, but material attributes (paper texture, odour, physical repairs) remain accessible only via the original.

Misapplication

Mistaken interpretation: treating digitization as identical to digital preservation or as restoring an item to like‑new condition. Semantic error: assuming a single capture guarantees long‑term usability, authenticity, or that the physical object is no longer necessary.

Consequence

Digitization increases access, enables text extraction and digital scholarship, and can reduce physical handling; causally it introduces new responsibilities (file management, metadata, rights management, storage) and can create false confidence about authenticity or permanence if preservation is not planned.

Reversal

Digitization is inappropriate or counterproductive when the handling required by capture poses greater risk to an object than leaving it undisturbed, or when the item’s essential significance resides in tactile, chemical, or three‑dimensional properties that cannot be represented digitally.

Boundary

Clearly within: creating preservation‑grade digital masters (e.g., high‑resolution images with technical metadata) of physical items. Boundary case: low‑quality photographic copies made only for quick access versus preservation masters. Clearly outside: born‑digital publications (not a conversion) or conservation treatments on the physical object.

Semantic Tension

Access versus authenticity/materiality: digitization broadens access but can create an impression of equivalence to the original that obscures material features and provenance significance.

Synthesis

Digitization produces usable representations that shift some uses from the original to digital forms; its value depends on capture quality, metadata, and integration with preservation and rights management rather than on capture alone.
