BS 4971:2002 pdf free.Repair and allied processes for the conservation of documents-Recommendations.
BS 4971 1 Scope This British Standard gives recommendations for remedial treatments and allied processes for use in the conservation of documents that have a long term value and are held in archives, libraries or private collections. It is not applicable to photographs, works of art on paper or electronic media.
NOTE Information about the storage of various kinds of photographic material is given in BS 1153. Photographic film of archival quality is specified in BS 5699.1 and BS 5699-2.
The standard is applicable to treatments that might be necessary to ensure the continued preservation of paper, parchment and seals. Methods of treatment are explained in detail only if information about them is not easily available elsewhere.
These recommendations apply to the conservation of documents in the United Kingdom but might be appropriate for other countries with similar, temperate climates.

Custodians of archive and library materials are responsible for maintaining the integrity of the documents in their care. This means preserving the textual, pictorial and physical content and character of the documents.
Changes to the original arising from unnecessary or inappropriate conservation interventions can destroy unique and important evidence of the document’s status, production, historical context and provenance. This compromises the document’s value to research, and in the case of an archival document undermines its legal authenticity.BS 4971 pdf download.
