Archives & Historical Records Preservation: Archival Science & NAI Guide
An archive is an institutional repository, physical facility, or digital repository dedicated to the systematic appraisal, accessioning, conservation, and scholarly dissemination of non-current documentary materials possessing permanent historical, legal, cultural, or evidentiary value. Unlike libraries—which primarily collect published, mass-produced books categorized by subject taxonomy—archives house unique, unpublished primary source records generated organically by governmental bodies, courts, corporate institutions, and notable individuals during their routine operations. Archival science is governed by two foundational principles formulated in European archival theory: the Principle of Provenance (respect des fonds), dictating that records originating from a single entity must remain unified and never intermingled with records from other creators; and the Principle of Original Order, mandating that documentary files be maintained in the exact sequence and internal organization established by the originating office.
The physical preservation of historical paper, parchment, and palm-leaf manuscripts requires rigorous environmental control and chemical conservation. Primary records are stored inside specialized climate-controlled archival repositories maintained at a constant temperature of eighteen to twenty degrees Celsius and a relative humidity of forty-five to fifty percent to prevent brittle paper degradation and fungal infestation. Conservation laboratories apply chemical deacidification using calcium hydroxide or barium hydroxide solutions to neutralize acidic breakdown products in aged wood-pulp paper. Fragile or torn folios are reinforced through delicate tissue lamination using handmade Japanese tissue paper and cellulose acetate paste, while atmospheric mold and insect pests are eliminated via non-destructive vacuum fumigation chambers.
In India, national documentary heritage is curated by the National Archives of India (NAI), headquartered in New Delhi as an attached office of the Ministry of Culture. Established on March 11, 1891, in Calcutta as the Imperial Record Department under the custodianship of G.W. Forrest, the institution was transferred to its landmark heritage building in New Delhi designed by Sir Edwin Lutyens in 1911. The statutory management of public records across central government ministries, public sector undertakings, and commissions is governed by the Public Records Act, 1993 and Public Records Rules, 1997. In the twenty-first century, the NAI has undertaken massive digital preservation campaigns under the "Abhilekh Patal" portal, making millions of digitized historical records accessible to global researchers, complementing UNESCO's Memory of the World Programme in safeguarding documentary memory.

An archive is a collection of primary source documents and records preserved for permanent historical, legal, and research value.
The term "archive" originates from the Greek word "archeion," designating the residence or office of the chief magistrate where public records were kept.
Unlike libraries that curate published literature, archives preserve unique, unpublished primary records generated during organizational activities.
The Principle of Provenance (respect des fonds) mandates that records from one creator must be kept distinct and not mixed with others.
The Principle of Original Order dictates that records must be preserved in the filing order and arrangement created by the originating agency.
The National Archives of India (NAI) is the premier archival repository of the Government of India, operating under the Ministry of Culture.

Public records are generally declassified and transferred to the National Archives of India after twenty-five years, subject to national security scrutiny.
Archival storage vaults maintain a strict climate of 18°C–20°C temperature and 45%–50% relative humidity to arrest chemical decay.
Chemical deacidification neutralizes acid built up in wood-pulp paper using alkaline solutions of calcium hydroxide or magnesium bicarbonate.
Tissue lamination reinforces fragile and brittle historical documents using fine Japanese tissue paper and cellulose acetate adhesive.
Vacuum fumigation utilizes inert gases or specialized compounds inside airtight chambers to eliminate silverfish, booklice, and mold spores.
Abhilekh Patal is the official search portal of the National Archives of India, providing digital access to millions of cataloged records.
The NAI is the largest archival repository in South Asia, holding millions of linear meters of historical files, treaties, maps, and private papers.
The Open Archival Information System (OAIS) reference model (ISO 14721) establishes international technical standards for digital record repositories.
