In library and archival science, preservation is a set of activities aimed at prolonging the life of a record, book, or object while making as few changes as possible. Preservation activities vary widely and may include monitoring the condition of items, maintaining the temperature and humidity in collection storage areas, writing a plan in case of emergencies, digitizing items, writing relevant metadata, and increasing accessibility. Preservation, in this definition, is practiced in a library or an archive by a librarian, archivist, or other professional when they perceive a record is in need of care.

Collections care, which is sometimes called preventive conservation, involves any actions taken to prevent or delay the deterioration of cultural heritage. The primary goal is to identify and reduce potential hazards to heritage with thoughtful control of their surroundings. The professions most influenced by collections care include conservator-restorers, curators, collection managers, and registrars.

Collection maintenance is a form of collections care that consists of the day-to-day hands on care of collections and cultural heritage. The primary goal of collections maintenance is to prevent further decay of cultural heritage by ensuring proper storage and upkeep including performing regular housekeeping of the spaces and objects and monitoring and controlling storage environments. Collections maintenance is closely linked to collections care and collections management. The professionals most influenced by collections maintenance include collection managers, registrars, and archivists.

Collections management involves the development, storage, and preservation of collections and cultural heritage. The primary goal of collections management is to meet the needs of the individual collector or collecting institution's mission statement, while also ensuring the long-term safety and sustainability of the cultural objects within the collector's care. Collections management, which consists primarily of the administrative responsibilities associated with collection development, is closely related to collections care, which is the physical preservation of cultural heritage.

The conservation and restoration of books, manuscripts, documents and ephemera is an activity dedicated to the preservation and protection of items of historical and personal value made primarily from paper, parchment, and leather. When applied to cultural heritage, conservation activities are generally undertaken by a conservator. The primary goal of conservation is to preserve the lifespan of the object as well as maintaining its integrity by keeping all additions reversible. Conservation of books and paper involves techniques of bookbinding, restoration, paper chemistry, and other material technologies including preservation and archival techniques.

Conservation and restoration of Mesoamerican codices is the process of analyzing, preserving, and treating codices for future study and access. It is a decision-making process that aims to establish the best possible methods and tools of preservation and treatment. The conservation-restoration of Mesoamerican literature is essential for understanding the ancient civilizations of Mexico. Efforts of restoration have proved difficult due to their fragility and importance of preserving historical and evidential value. Non-invasive technologies have been a more recent advancement, making analysis and treatment of pre-Hispanic codices a delayed process. As analysis continues, digitization has also been a more recent and valuable means of making information accessible to a wider audience, thus contributing to further research and preservation.

Double Fold: Libraries and the Assault on Paper is a non-fiction book by Nicholson Baker that was published in April 2001. An excerpt appeared in the July 24, 2000 issue of The New Yorker, under the title "Deadline: The Author's Desperate Bid to Save America's Past." This exhaustively researched work details Baker's quest to uncover the fate of thousands of books and newspapers that were replaced and often destroyed during the microfilming boom of the 1980s and 1990s. Double Fold is a controversial work and is not meant to be objective. In the preface, Baker says, "This isn't an impartial piece of reporting", and The New York Times characterized the book as a "blistering and thoroughly idiosyncratic attack".

The International Dunhuang Project (IDP) is an international collaborative effort to conserve, catalogue and digitise manuscripts, printed texts, paintings, textiles and artefacts from the Mogao caves at the Western Chinese city of Dunhuang and various other archaeological sites at the eastern end of the Silk Road. The project was established by the British Library in 1994, and now includes twenty-two institutions in twelve countries. As of 18 February 2021 the online IDP database comprised 143,290 catalogue entries and 538,821 images. Most of the manuscripts in the IDP database are texts written in Chinese, but more than fifteen different scripts and languages are represented, including Brahmi, Kharosthi, Khotanese, Sanskrit, Tangut, Tibetan, Tocharian and Old Uyghur.
