Inherent Vice (library And Archival Science), Inherent Vice
Inherent vice is the tendency in physical objects to deteriorate because of the fundamental instability of the components of which they are made, as opposed to deterioration caused by external forces. All objects have some kind of inherent vice as a result of the baseline law of entropy. Preservation issues The term is broadly used in archival practice to recognize the material constraints of preservation activities. For example, many kinds of paper have acid in them that makes them chemically unstable. Over time, the acid will eat away the text on the page and cause paper to turn yellow or brown and become brittle. As the acid continues to break down the cellulose fibers, the paper disintegrates. In the world of philately, the adhesive on the back of stamps is both an inherent vice—any exposure to moisture will compromise their ability to be preserved—as well as the purpose for which the stamps were made. In the case of film, an example of inherent vice is the innate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Entropy
Entropy is a scientific concept, most commonly associated with states of disorder, randomness, or uncertainty. The term and the concept are used in diverse fields, from classical thermodynamics, where it was first recognized, to the microscopic description of nature in statistical physics, and to the principles of information theory. It has found far-ranging applications in chemistry and physics, in biological systems and their relation to life, in cosmology, economics, sociology, weather science, climate change and information systems including the transmission of information in telecommunication. Entropy is central to the second law of thermodynamics, which states that the entropy of an isolated system left to spontaneous evolution cannot decrease with time. As a result, isolated systems evolve toward thermodynamic equilibrium, where the entropy is highest. A consequence of the second law of thermodynamics is that certain processes are irreversible. The thermodynami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archival Science
Archival science, or archival studies, is the study and theory of building and Curator, curating archives, which are collections of documents, Sound recording and reproduction, recordings, photographs and various other materials in physical or digital formats. To build and curate an archive, one must acquire and evaluate the materials, and be able to access them later. To this end, archival science seeks to improve methods for Archival appraisal, appraising, storing, Preservation (library and archival science), preserving, and Archival processing, processing (arranging and describing) collections of materials. An archival record preserves data that is not intended to change. In order to be of value to society, archives must be trustworthy. Therefore, an archivist has a responsibility to authenticate archival materials, such as historical documents, and to ensure their reliability, integrity, and usability. Archival records must be what they claim to be; accurately represent the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Preservation (library And Archival Science)
In Conservation and restoration of cultural property, conservation, Library science, library and archival science, preservation is a set of preventive conservation activities aimed at prolonging the life of a record, book, or object while making as few changes as possible. Preservation activities vary widely and may include monitoring the condition of items, maintaining the temperature and humidity in collection storage areas, writing a plan in case of emergencies, digitizing items, writing relevant metadata, and increasing accessibility. Preservation, in this definition, is practiced in a library or an archive by a Conservator-restorer, conservator, librarian, archivist, or other professional when they perceive a collection or record is in need of maintenance. Preservation should be distinguished from interventive Conservation and restoration of books, manuscripts, documents and ephemera, conservation and restoration, which refers to the treatment and repair of individual items ...

Cellulose
Cellulose is an organic compound with the chemical formula, formula , a polysaccharide consisting of a linear chain of several hundred to many thousands of glycosidic bond, β(1→4) linked glucose, D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most abundant biopolymer, organic polymer on Earth. The cellulose content of cotton fibre is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%. Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and rayon. Conversion of cellulose from energy crops into biofuels such as cellulosic ethanol is under development as a renewable fuel source. Cellulose for industrial use is mainly obtained from wood pulp and cotton. Cellulose is also greatly affected by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philately
Philately (; ) is the study of postage stamps and postal history. It also refers to the collection and appreciation of stamps and other philatelic products. While closely associated with stamp collecting and the study of postage, it is possible to be a philatelist without owning any stamps. For instance, the stamps being studied may be very rare or reside only in museums. Etymology The word "philately" is the English transliteration of the French "", coined by Georges Herpin in 1864. Herpin stated that stamps had been collected and studied for the previous six or seven years and a better name was required for the new hobby than ''timbromanie'' (roughly "stamp mania"), which was disliked.Williams, L.N. & M. ''Fundamentals of Philately''. State College: The American Philatelic Society, 1971, p. 20. The alternative terms "timbromania", "timbrophily", and "timbrology" gradually fell out of use as ''philately'' gained acceptance during the 1860s. Herpin took the Greek root word φ ...

Cellulose Acetate Film
Cellulose acetate film, or safety film, is used in photography as a base material for photographic emulsions. It was introduced in the early 20th century by film manufacturers and intended as a safe film base replacement for unstable and highly flammable nitrate film. Cellulose diacetate film was first employed commercially for photographic film in 1909. Cellulose acetate propionate and cellulose acetate butyrate were introduced in the 1930s, and cellulose triacetate in the late 1940s. Acetate films were later replaced by polyester bases. The motion picture industry continued to use cellulose nitrate supports until the introduction of cellulose triacetate in 1948, which met the rigorous safety and performance standards set by the cinematographic industry. The chemical instability of cellulose acetate material, unrecognized at the time of its introduction, has since become a major problem for film archives and collections. History Cellulose diacetate film was first created by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vinegar Syndrome
Vinegar Syndrome is an American home video distribution company which specializes in "protecting and preserving genre films". The company was founded in 2012 in Bridgeport, Connecticut by Joe Rubin and Ryan Emerson, who created it to restore and distribute old X-rated films that were lost or otherwise unavailable. Their catalog has since expanded to include other types of cult and exploitation films, including horror films and action films. Vinegar Syndrome has been compared to the Criterion Collection for its importance to "physical media and film preservation," as well as similarly garnering praise for high-quality home video offerings. Like the Criterion Collection, Vinegar Syndrome is considered a boutique Blu-ray label. In September 2021, Vinegar Syndrome announced the establishment of Vinegar Syndrome Pictures (VSP), a sub-branding dedicated to the production and distribution of films. The first film released under the VSP banner was '' New York Ninja'', which was shot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corrosion
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion. In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen, hydrogen, or hydroxide. Rusting, the formation of red-orange iron oxides, is a well-known example of electrochemical corrosion. This type of corrosion typically produces oxides or salts of the original metal and results in a distinctive coloration. Corrosion can also occur in materials other than metals, such as ceramics or polymers, although in this context, the term "degradation" is more common. Corrosion degrades the useful properties of materials and structures including mechanical strength, appearance, and permeability to liquids and ga ...
