The conservation and restoration of books, manuscripts, documents, and ephemera is an activity dedicated to extending the life 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.
For the purposes of conservation and restoration, the term parchment is used in reference to vellum objects, as the terms have been used interchangeably throughout time to refer to objects with the same conservation concerns. [2] Parchment has unique structural qualities which differentiate it from paper-based materials.
1933: William Barrow introduces the field of conservation to paper deacidification when he publishes a paper on the acid paper problem. In later studies, Barrow tested paper from American books made between 1900 and 1949, and learned that after forty years the books had lost on average 96 percent of their original strength; after less than ten ...
Media preservation. Preservation of documents, pictures, recordings, digital content, etc., is a major aspect of archival science. It is also an important consideration for people who are creating time capsules, family history, historical documents, scrapbooks and family trees. Common storage media are not permanent, and there are few reliable ...
William Barrow (chemist) William James Barrow (December 11, 1904 – August 25, 1967) [1] was an American chemist and paper conservator, and a pioneer of library and archives conservation. He introduced the field of conservation to paper deacidification through alkalization.
Manuscript preservation may also take the form of digital archiving, which is particularly useful for vulnerable manuscripts and fragments susceptible to deterioration such as the burnt fragments extant from the Cotton library fire which have now been recorded using multispectral imaging by the British Library.

Acid-free paper is paper that, if infused in water, yields a neutral or basic pH (7 or slightly greater). It can be made from any cellulose fiber as long as the active acid pulp is eliminated during processing. It is also lignin - and sulfur -free. [1] Acid-free paper addresses the problem of preserving documents and preserving artwork for long ...
Using blotting paper, the papyri fragments are dried via sheets of blotting paper. Using Paraloid B-48 (20 percent in acetone), the painting and its gesso layer are consolidated from the back. The object is then backed by a new cartonnage support consisting of Japanese paper (70–90 grams), linen cloth and a Planatol BB/water dilution (40 ...
