Documentation science includes many methods that help people collect, organize, store, and find information. These practices are used in libraries, archives, research labs, companies, and now also in online systems.
Collecting and creating documents In the past, documentation work included gathering books, articles, reports, and other printed materials. People created records of these materials manually, using catalog cards, indexes, or bibliographies.
Paul Otlet’s work with the Universal Bibliographic Repertory is one example. He created millions of card entries to organize knowledge from around the world. Today, documents are not only created by humans. Computers and machines also generate documents, like log files, metadata, and sensor data. These need new tools and methods for collection and management.
Organizing information Organizing documents has always been a foundational element of documentation science. Methods like
classification (dividing things into groups) and indexing (making lists of topics or keywords) help individuals find what they need. A widely used system is the
Universal Decimal Classification (LCC) used in the majority of U.S. libraries. Indexing can be performed by humans or by software programs that read the text and add tags to documents.
Metadata is also used to describe documents.
Metadata is “data about data” like the title, author, date, and subject of a document. Standards like
Dublin Core are used in digital libraries to keep metadata consistent.
Retrieval and access One of the main objectives of documentation is helping users find the right document. This is called
information retrieval. In the past, this meant using catalog drawers or printed indexes. Today, people use search engines, databases, and digital libraries. Modern retrieval tools use Boolean logic, ranking algorithms, and sometimes
machine learning to show the most useful results first. This is part of what is studied in both documentation science and information retrieval.
Preservation and archiving Documents require long-term storage. This is called
preservation of documents. Printed documents can be damaged by light, pests, or even time on the other hand digital documents can be deemed worthless if formats become outdated or storage facilities fail. Archivists use methods like migration, which includes moving files to new formats, and emulation, which replicates obsolete systems, to preserve materials. These methods and tools are ever changing as new technologies develop. But the main objective of documentation has remained the same, which is to keep information safe, organized, and easy to find. == Documentation in the digital age ==
