Slow Fire
A slow fire is a term used in library and information science to describe paper embrittlement resulting from acid decay. The term is taken from the title of Terry Sanders's 1987 film ''Slow Fires: On the preservation of the human record.'' Solutions to this problem include the use of acid-free paper stocks, reformatting brittle books by microfilming, photocopying or digitization, and a variety of deacidification techniques.

Book Suffering From Slow Fire
A book is a medium for recording information in the form of writing or images, typically composed of many pages (made of papyrus, parchment, vellum, or paper) bound together and protected by a cover. The technical term for this physical arrangement is '' codex'' (plural, ''codices''). In the history of hand-held physical supports for extended written compositions or records, the codex replaces its predecessor, the scroll. A single sheet in a codex is a leaf and each side of a leaf is a page. As an intellectual object, a book is prototypically a composition of such great length that it takes a considerable investment of time to compose and still considered as an investment of time to read. In a restricted sense, a book is a self-sufficient section or part of a longer composition, a usage reflecting that, in antiquity, long works had to be written on several scrolls and each scroll had to be identified by the book it contained. Each part of Aristotle's ''Physics'' is called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Library And Information Science
Library and information science(s) or studies (LIS) is an interdisciplinary field of study that deals generally with organization, access, collection, and protection/regulation of information, whether in physical (e.g. art, legal proceedings, etc.) or digital forms. In spite of various trends to merge the two fields, some consider the two original disciplines, library science and information science, to be separate. However, it is common today to use the terms synonymously or to drop the term "library" and to speak about ''information departments'' or '' I-schools''. There have also been attempts to revive the concept of documentation and to speak of Library, information and documentation studies (or science). History By the late 1960s, mainly due to the meteoric rise of human computing power and the new academic disciplines formed therefrom, academic institutions began to add the term "information science" to their names. The first school to do this was at the University o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paper
Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year. It is a versatile material with many uses, including printing, painting, graphics, signage, design, packaging, decorating, writing, and cleaning. It may also be used as filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, or currency and security paper, or in a number of industrial and construction processes. The papermaking process developed in east Asia, probably China, at least as early as 105 CE, by the Han court eunuch Cai Lun, al ...

Acid-free Paper
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. Acid-free paper addresses the problem of preserving documents and preserving artwork for long periods. Overview Paper made from wood-based pulp that has not had its lignin removed turns yellow, becomes brittle, and deteriorates over time. When exposed to light and/or heat, the molecules in the acidic paper will break down even faster. Acidic wood-pulp paper became commonplace in the late 19th century, and in the 1930s William Barrow (a chemist and librarian) published a report about the deterioration of acidic paper in the libraries. For fear of the gradual disintegration of written materials, measures have since been taken to improve the quality of paper. During production, acid-free paper may be treated with a mild base (usuall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mass Deacidification
Mass deacidification is a term used in library and information science as one possible measure against the degradation of paper in old books, the so-called " slow fires". The goal of the process is to increase the pH of acidic paper. Although acid-free paper has become more common, a large body of acidic paper still exists in books made after the 1850s; this is because of its cheaper and simpler production methods. Acidic paper, especially when exposed to light, air pollution, or high relative humidity, yellows and becomes brittle over time. During mass deacidification an alkaline agent is deposited in the paper to neutralize existing acid and prevent further decay. Mass deacidification is intended for objects on acidic paper that will be lost if no action is performed. History of research and process development Mass deacidification — along with microfilm and lamination — was developed during the early and mid-20th century as a response to the chemical process o ...

Acidic Paper
Acidic paper is paper that had some acidic substances used during the manufacture process. This type of paper, widely used since the mid-nineteenth century, turns yellow in a short time and becomes extremely brittle, which causes huge losses in library and archives collections. Causes of paper degradation Paper degradation is a slow process, but it is significantly accelerated in an acidic environment. In the mid-nineteenth century, the method of paper production became popular, in which resin- alum glue was added to the paper pulp. The aluminum sulphate remaining in the paper form, in reaction with water, acids that catalyze the decomposition of cellulose (acidic hydrolysis). In this process, the cellulose chains are shortened, which reduces the tear resistance of the paper, and at the same time increases the cross-linking of their structure that causes the paper to stiffen and become brittle. Parallel to the degradation under the influence of water, the cellulose chains react ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Double Fold
''Double Fold: Libraries and the Assault on Paper'' is a non-fiction book by Nicholson Baker that was published in April 2001. An excerpt appeared in the July 24, 2000 issue of ''The New Yorker'', under the title "Deadline: The Author's Desperate Bid to Save America's Past." This exhaustively researched work (there are 63 pages of endnotes and 18 pages of references in the paperback edition) details Baker's quest to uncover the fate of thousands of books and newspapers that were replaced and often destroyed during the microfilming boom of the 1980s and 1990s. ''Double Fold'' is a controversial work and is not meant to be objective. In the preface, Baker says, "This isn't an impartial piece of reporting", (preface p. x) and ''The New York Times'' characterized the book as a "blistering and thoroughly idiosyncratic attack". Overview The term " double fold" refers to the test used by many librarians and preservation administrators to determine the brittleness and "usability" of pap ...

Wood-pulp Paper
Pulp is a lignocellulosic fibrous material prepared by chemically or mechanically separating cellulose fibers from wood, fiber crops, waste paper, or rags. Mixed with water and other chemical or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other paper products. History Before the widely acknowledged invention of papermaking by Cai Lun in China around 105 AD, paper-like writing materials such as papyrus and amate were produced by ancient civilizations using plant materials which were largely unprocessed. Strips of bark or bast material were woven together, beaten into rough sheets, dried, and polished by hand. Pulp used in modern and traditional papermaking is distinguished by the process which produces a finer, more regular slurry of cellulose fibers which are pulled out of solution by a screen and dried to form sheets or rolls. The earliest paper produced in China consisted of bast fibers from the paper mul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Library And Archival Science
A library is a collection of materials, books or media that are accessible for use and not just for display purposes. A library provides physical (hard copies) or digital access (soft copies) materials, and may be a physical location or a virtual space, or both. A library's collection can include printed materials and other physical resources in many formats such as DVD, CD and cassette as well as access to information, music or other content held on bibliographic databases. A library, which may vary widely in size, may be organized for use and maintained by a public body such as a government; an institution such as a school or museum; a corporation; or a private individual. In addition to providing materials, libraries also provide the services of librarians who are trained and experts at finding, selecting, circulating and organizing information and at interpreting information needs, navigating and analyzing very large amounts of information with a variety of resources.
