The term "Hollinger" refers to the manufacturer, Hollinger Metal Edge, a company founded in 1945 in Arlington, Virginia. Hollinger Metal Edge worked with officials at the Library of Congress and National Archives of the United States to develop acid free papers, storage boxes and envelopes that would preserve archival collections.

A paper conservator surveying a collection of materials in storage. Storage in a cool, dry, clean, and stable location can extend the life of an item. [51] Manuscripts and paper documents are often stored in protective archival-quality boxes and folders, made of acid-free and lignin-free materials. [52]
All materials should be acid-free for conservation. The depth of the box is normally about five inches, if it is not made for a specific object, and various standard sizes are made, with traditional names including "royal", "imperial", "elephant" and others. Ones for very old books will typically be custom made to an exact size.
High-Density Rosetta (HD-Rosetta) is a permanent data storage device which contains engraved microscopic information on a small 3-inch (7.6 cm) nickel plate. Up to 196,000 8.5×11 in (22×28 cm) pages of information can be stored onto the plate using a focused ion beam.
The full title of EN 16893:2018 is Conservation of Cultural Heritage - Specifications for location, construction and modification of buildings or rooms intended for the storage or use of heritage collections. For archival and library collections (the original sector at which 5454 was aimed), a reviewed standard, BS 4971, was released in 2017.
The company Hercules Incorporated developed the first alkaline sizing in the 1950s that made acid-free paper possible. [10] Despite the advances in paper making and the identification of and concern around the brittle book problem, it took decades before the adoption of ANSI NISO Standard Z39.48-1984 - Permanence of Paper for Publications and Documents in Libraries in 1984.
Polyester sleeves, acid-free folders, and pH buffered document boxes are common supportive protective enclosures whose selection must match the media's chemical and physical properties. [1] Other considerations in preserving paper/books are: Damaging light, particularly UV light, which fades and destroys media over time by breaking down the ...
Mass deacidification—along with microfilm and lamination—was developed during the early and mid-20th century as a response to the chemical process of hydrolysis by which the fibers that constitute paper, providing its structure and strength, have their bonds broken, resulting in paper that becomes increasingly brittle over time.
