(Austrian State Archive), in the Erdberg district of Vienna (2006) Historians,
genealogists, lawyers,
demographers, filmmakers, and others conduct research at archives. The research process at each archive is unique and depends upon the institution that houses the archive. While there are many kinds of archives, the most recent census of archivists in the United States identifies five major types:
academic,
business (for profit),
government,
non-profit, and
others. There are also four main areas of inquiry involved with archives: material technologies, organizing principles, geographic locations, and tangled embodiments of humans and non-humans. These areas help to further categorize what kind of archive is being created.
Academic Regional Archives Archives in colleges, universities, and other educational facilities are typically housed within a library, and duties may be carried out by an
archivist. Academic archives exist to preserve institutional history and serve the academic community. An academic archive may contain materials such as the institution's administrative records, personal and professional papers of former professors and presidents, memorabilia related to school organizations and activities, and items the academic library wishes to remain in a closed-stack setting, such as rare books or
thesis copies. Access to the collections in these archives is usually by prior appointment only; some have posted hours for making inquiries. Users of academic archives can be undergraduates, graduate students, faculty and staff, scholarly researchers, and the general public. Many academic archives work closely with
alumni relations departments or other campus institutions to help raise funds for their library or school. Qualifications for employment may vary. Entry-level positions usually require an undergraduate diploma, but typically archivists hold graduate degrees in history or library science (preferably certified by a body such as the
American Library Association). Subject-area specialization becomes more common in higher-ranking positions.
Business (for profit) Archives located in for-profit institutions are usually those owned by a private business. Examples of prominent business archives in the United States include
Coca-Cola (which also owns the separate museum
World of Coca-Cola),
Procter and Gamble,
Motorola Heritage Services and Archives, and
Levi Strauss & Co. These corporate archives maintain historic documents and items related to the history and administration of their companies. Business archives serve the purpose of helping corporations maintain control over their brand by retaining memories of the company's past. Especially in business archives,
records management is separate from the historical aspect of archives. Workers in these types of archives may have any combination of training and degrees, from either a history or library background. These archives are typically not open to the public and are only used by workers of the owner company, though some allow approved visitors by appointment. Business archives are concerned with maintaining the
integrity of their company and are therefore selective about how their materials may be used.
Government , Washington, D.C. Government archives include those maintained by local and state governments as well as those maintained by the national (or federal) government. Anyone may use a government archive, and frequent users include
reporters,
genealogists, writers,
historians, students, and people seeking information on the history of their home or region. Many government archives are open to the public, and no appointment is required to visit. In the United States, the
National Archives and Records Administration (NARA) maintains central archival facilities in the
District of Columbia and
College Park, Maryland, with regional facilities distributed throughout the United States. Some city or local governments may have repositories, but their organization and accessibility vary widely. Similar to the library profession, certification requirements and education also varies widely, from state to state. Professional associations themselves encourage the need to professionalize. NARA offers the Certificate of Federal Records Management Training Program for professional development. The majority of state and local archives staff hold a
bachelor's degree—increasingly repositories list advanced degrees (e.g. MA, MLS/MLIS, Ph.D.) and certifications as a position requirement or preference. The
English Heritage Archive is the public archive of
English Heritage. The
National Records of Scotland, located in
Edinburgh, serves that country; while the
Public Record Office of Northern Ireland in
Belfast is the government archive for Northern Ireland. A network of
county record offices and other local authority-run archives exists throughout England, Wales, and Scotland and holds many important collections, including local government, landed estates, church, and business records. Many archives have contributed catalogs to the national "
Access to Archives" program and online searching across collections is possible. In France, the French Archives Administration (
Service interministériel des Archives de France) in the
Ministry of Culture supervises the
National Archives (
Archives nationales), which possess of physical records (the total length of occupied shelves put next to each other), with original records going as far back as A.D. 625, and 74.75 terabytes (74,750
GB) of electronic archives, as well as the
National Overseas Archives (ANOM, of physical records), the (ANMT, of physical records), and all local public archives (departmental archives, or
archives départementales, located in the
préfectures of each of the 100
départements of France plus the City of Paris, more than 400 municipal archives in the larger towns and cities of France, and 12 newer regional archives) which possess of physical records and 225.25 terabytes of electronic archives (). Put together, the total volume of archives under the supervision of the French Archives Administration is the largest in the world. The archives of the French
Ministry of Armed Forces (
Defence Historical Service, ca. of physical records) and the archives of the French
Ministry of Foreign Affairs (, ca. of physical records) are managed separately by their respective ministries and do not fall under the jurisdiction of the Archives of France Administration. In
India, the
National Archives (NAI) are located in New Delhi. In
Taiwan, the National Archives Administration are located in
Taipei. Most intergovernmental organizations keep their own historical archives. However, a number of European organizations, including the European Commission, choose to deposit their archives with the European University Institute in Florence.
Church A prominent church archive is the
Vatican Apostolic Archive.
Archdioceses,
dioceses, and parishes also have archives in the Roman Catholic and
Anglican Churches. Very important are
monastery archives because of their antiquity, like the ones of
Monte Cassino,
Saint Gall, and
Fulda. The records in these archives include manuscripts, papal records, local church records, photographs, oral histories, audiovisual materials, and architectural drawings. Most Protestant denominations have archives as well, including the
Presbyterian Historical Society, the Moravian Church Archives, the Southern Baptist Historical Library and Archives, the United Methodist Archives and History Center of the United Methodist Church, and the Christian Church (Disciples of Christ).
Motion pictures, film, and audio and video tape Film archives collect, restore, investigate and conserve audiovisual content like films, documentaries, tv programs and newsreel footage. Often, a country has its own film archive to preserve its national audiovisual heritage. The
International Federation of Film Archives comprises more than 150 institutions in over 77 countries and the
Association of European Film Archives and Cinematheques is an affiliation of 49 European national and regional film archives founded in 1991. For a comprehensive look at the history of film preservation and the institutions and organizations that developed various practices, see

Keepers of the Frame. Non-profit Non-profit archives include those in
historical societies, not-for-profit businesses such as hospitals, and repositories within
foundations. Such repositories are typically set up with private funds from donors to preserve the papers and histories of specific people or places. These institutions may rely on
grant funding from the government as well as private funds. Depending on the availability of funds, non-profit archives may be as small as the historical society in a rural town to as big as a state historical society that rivals a government archive. Users of this type of archive may vary as much as the institutions that hold it. Employees of non-profit archives may be professional archivists,
paraprofessionals, or volunteers, as the education required for a position at a non-profit archive varies with the demands of the collection's user base.
Web archiving Web archiving is the process of collecting portions of the
World Wide Web and ensuring the collection is
preserved in an archive, such as an
archive site, for future researchers, historians, and the public. Due to the massive size of the Web, web archivists typically employ
web crawlers for automated collection. Similarly, software code and documentation can be archived on the web, as with the example of
CPAN.
Dark archives Archives that are collected and kept in cold storage (i.e., not openly accessible) are sometimes called
dark archives. For example in 2025, the academic paper repository
arXiv was concerned about trends in the United States and elsewhere that might restrict academic freedoms. They created a dark archive of the website, so it could be reconstituted in another country, if required.
Dark archive is also used in library science for collections of online publications that are held in reserve in case the publisher no longer makes them available. Another type of archive is the Public Secrets project. This is an interactive testimonial, in which women incarcerated in the California State Prison System describe what happened to them. The archive's mission is to gather stories from women who want to express themselves and want their stories heard. This collection includes transcripts and an audio recording of the women telling their stories. The archives of an individual may include letters, papers, photographs, computer files, scrapbooks, financial records, or diaries created or collected by the individual, regardless of medium or format. The archives of an organization (such as a corporation or government) tend to contain other types of records, such as administrative files, business records, memos, official correspondence, and meeting minutes. Some archives are made up of a compilation of both types of collections. An example of this type of combined compilation is the
Transgender Archives at the University of Victoria, which contain a multitude of collections of donations from both individuals and organizations from all over the world. Many of these donations have yet to be cataloged but are currently in the process of being
digitally preserved and made available to the public online. The
Arctic World Archive is a commercially-run facility for data preservation located in the
Svalbard archipelago, Norway, that contains data of historical and cultural interest from several countries as well as all of American multinational company
GitHub's
open source code. The data is kept on reels of specially developed film in a steel vault buried deep beneath the
permafrost, with the data storage medium expected to last for 500 to 1000 years. ==Standardization==
