Digitization is the process of converting analog materials like books, papers, and other documents into a digital format that can be understood and manipulated by computers. Some key reasons for digitizing documents include preserving them, making them more accessible, and allowing them to be reused. When deciding whether to digitize documents, factors to consider include whether the documents are worth digitizing, who the target audience is, if the documents form a coherent collection, and how easy they are to digitize.
