is an exhibition space of works in a gallery that charges the artist for use of the space. Temporary museum exhibitions typically display items from the museum's own collection on a particular period, theme or topic, supplemented by loans from other collections, mostly those of other museums. They normally include no items for sale; they are distinguished from the museum's permanent displays, and most large museums set aside a space for temporary exhibitions. Exhibitions in commercial galleries are often entirely made up of items that are for sale, but may be supplemented by other items that are not. Typically, the visitor has to pay (extra on top of the basic museum entrance cost) to enter a museum exhibition, but not a commercial one in a gallery.

History

The art exhibition has played a crucial part in the market for new art since the 18th and 19th centuries. The

Paris Salon The Salon (french: Salon), or rarely Paris Salon (French: ''Salon de Paris'' ), beginning in 1667 was the official art exhibition of the Académie des Beaux-Arts in Paris. Between 1748 and 1890 it was arguably the greatest annual or biennial ar ...

. In 1968, Art fairs in Europe became quite the fashion with the advent of the Cologne Art Fair which was sponsored by the Cologne Art Dealers Association. Because of the high admission standards of the Cologne fair a rival fair was organized in Düsseldorf which enabled less regarded galleries opportunity to meet with an international public. The fairs took place during the fall months. This rivalry continued for a few years which provided the Basel Art Fair the opportunity to interject the Basel fair in early summer. These fairs became extremely important to galleries, dealers and publishers as they provided the possibility of worldwide distribution. Düsseldorf and Cologne merged their efforts. Basel soon became the most important art fair. In 1976, the Felluss Gallery under the direction of Elias Felluss, in Washington DC organized the first American dealer art fair. "The Washington International Art Fair" or "Wash Art" for brevity. This American fair met with fierce opposition by those galleries interested in maintaining distribution channels for European artwork already in place. The Washington fair introduced the European idea of dealer fairs to art dealers throughout the United States. Following the advent of Wash Art, many fairs developed throughout the United States.

Preservation issues

Although preservation issues are often disregarded in favor of other priorities during the exhibition process, they should certainly be considered so that possible damage to the collection is minimized or limited. As all objects in the library exhibition are unique and to some extent vulnerable, it is essential that they be displayed with care. Not all materials are able withstand the hardships of display, and therefore each piece needs to be assessed carefully to determine its ability to withstand the rigors of an exhibition. In particular, when exhibited items are archival artifacts or paper-based objects, preservation considerations need be emphasized because damage and change in such materials is cumulative and irreversible. Two trusted sources – the National Information Standard Organization's ''Environmental Conditions for Exhibiting Library and Archival Materials,'' and the British Library's ''Guidance for Exhibiting Library and Archive Materials'' – have established indispensable criteria to help curtail the deleterious effects of exhibitions on library and archival materials. These criteria may be divided into five main preservation categories: Environmental concerns of the exhibition space; Length of the exhibition; Individual cases; Display methods used on individual objects; and Security.

Environmental concerns of the exhibition space

The intensity of visible light in the display space should be low enough to avoid object deterioration, but bright enough for viewing. A patron's tolerance of low-level illumination can be aided by reducing ambient light levels to a level lower than that falling on the exhibit. Visible light levels should be maintained at between 50

s being exposed and the duration of the exhibition time. A maximum exhibition length should initially be determined for each exhibited item based on its light sensitivity, anticipated light level, and its cumulative past and projected exhibition exposure. Light levels need to be measured when the exhibition is prepared. UV light meters will check radiation levels in an exhibit space, and data event loggers help determine visible light levels over an extended period of time. Blue wool standards cards can also be utilized to predict the extent to which materials will be damaged during exhibits. UV

When such exposure is unavoidable, preventative measures must be taken to control UV radiation, including the use of blinds, shades, curtains, UV filtering films, and UV-filtering panels in windows or cases.

s, common in most institutions, may be used only when they produce a low UV output and when covered with plastic sleeves before exhibition. Though tungsten-halogen lamps are currently a favorite artificial lighting source, they still give off significant amounts of UV radiation; use these only with special UV filters and dimmers. Lights should be lowered or turned off completely when visitors are not in the exhibition space. ;Relative humidity (RH) The exhibition space's relative humidity (RH) should be set to a value between 35% and 50%. The maximum acceptable variation should be 5% on either side of this range. Seasonal changes of 5% are also allowed. The control of relative humidity is especially critical for

materials, which are extremely sensitive to changes in relative humidity and may contract violently and unevenly if displayed in too dry an environment. ;Temperature For preservation purposes, cooler temperatures are always recommended. The temperature of the display space should not exceed 72 °F. A lower temperature of down to 50 °F can be considered safe for a majority of objects. The maximum acceptable variation in this range is 5 °F, meaning that the temperature should not go above 77 °F and below 45 °F. As temperature and relative humidity are interdependent, temperature should be reasonably constant so that relative humidity can be maintained as well. Controlling the environment with 24-hour air conditioning and dehumidification is the most effective way of protecting an exhibition from serious fluctuations.

Length of the exhibition

One factor that influences how well materials will fare in an exhibition is the length of the show. The longer an item is exposed to harmful environmental conditions, the more likely that it will experience deterioration. Many museums and libraries have permanent exhibitions, and installed exhibitions have the potential to be on the view without any changes for years. Damage from a long exhibition is usually caused by light. The degree of deterioration is different for each respective object. For paper-based items, the suggested maximum length of time that they should be on display is three months per year, or 42

hours of light per year – whichever comes first.Adcock, ''IFLA Principles for the Care and Handling of Library Material'' (1998), 6. An exhibition log report, including records of the length of the exhibition time and the light level of the display, may prevent objects from being exhibited too frequently. Displayed items need to be inspected regularly for evidence of damage or change. It is recommended that high-quality facsimiles of especially delicate or fragile materials be displayed in lieu of originals for longer exhibitions.Nelly Balloffet and Jenny Hille, ''Preservation and Conservation for Libraries and Archives'' (Chicago: ALA, 2005), 37.

Individual cases

Library or archival materials are usually displayed in display cases or frames. Cases provide a physically and chemically secure environment. Vertical cases are acceptable for small or single-sheet items, and horizontal cases can be used for a variety of objects, including three-dimensional items such as opened or closed books, and flat paper items. All these objects can be arranged simultaneously in one horizontal case under a unified theme. Materials used for case construction should be chosen carefully because component materials can easily become a significant source of pollutants or harmful fumes for displayed objects. Outgassing from materials used in the construction of the exhibition case and/or fabrics used for lining the case can be destructive. Pollutants may cause visible deterioration, including discoloration of surfaces and

. Examples of evaluative criteria to be used in deeming materials suitable for use in exhibit display could be the potential of contact-transfer of harmful substances, water solubility or dry-transfer of dyes, the dry-texture of paints, pH, and abrasiveness. New cases may be preferred, constructed of safe materials such as metal, plexiglass, or some sealed woods. Separating certain materials from the display section of an exhibition case by lining relevant surfaces with an impermeable barrier film will help protect items from damage. Any fabrics that line or decorate the case (for example, polyester blend fabric), and any adhesives used in the process, should also be tested to determine any risk. Using internal buffers and pollutant absorbers, such as silica gel,

Display methods

There are two kinds of objects displayed at the library and archival exhibition – bound materials and unbound materials. Bound materials include

s, cards, drawings, and other two-dimensional items. The observance of proper display conditions will help minimize any potential physical damage. All items displayed must be adequately supported and secured. ;Unbound materials Unbound materials, usually single-sheet items, need to be attached securely to the mounts, unless matted or encapsulated. Metal fasteners, pins, screws, and thumbtacks should not come in direct contact with any exhibit items. Instead, photo corners,

film straps may hold the object to the support. Objects may also be encapsulated in polyester film, though old and untreated acidic papers should be professionally deacidified before encapsulation. Avoid potential slippage during encapsulation – when possible, use ultrasonic or heat seals. For objects that need to be hung (and that may require more protection than lightweight polyester film), matting would be an effective alternative. Objects in frames should be separated from harmful materials through matting, glazing, and backing layers. Matting, which consists of two pH-neutral or alkaline boards with a window cut in the top board to enable the object to be seen, can be used to support and enhance the display of single sheet or folded items. Backing layers of archival cardboard should be thick enough to protect objects. Moreover, any protective glazing used should never come in direct contact with objects. Frames should be well-sealed and hung securely, allowing a space for air circulation between the frame and the wall. ;Bound materials The most common way to display bound materials is closed and lying horizontally. If a volume is shown open, the object should be open only as much as its binding allows. Common practice is to open volumes at an angle no greater than 135°. There are some types of equipment that help support volumes as they displayed openly: blocks or wedges, which hold a book cover to reduce stain at the book hinge; cradles, which support bound volumes as they lay open without stress to the binding structure; and polyester film strips, which help to secure open leaves. Textblock supports are best used in conjunction with book cradles where the textblock is greater than 1/2 inch, or where the textblock noticeably sags. Regardless of its method of support, however, it is worth noting that any book that is kept open for long periods can cause damage. One should turn an exhibited book's pages every few days in order to protect pages from overexposure to light and spread any strain on the binding structure.

Security

Because exhibited items are often of special interest, they demand a high level of security to reduce the risk of loss from theft or vandalism. Exhibition cases should be securely locked. In addition, cases may be glazed with a material that hinders penetration and that when broken does not risk shards of glass falling on the exhibits. Whenever possible, the exhibition area should be patrolled; a 24-hour security presence is recommended when precious treasures are exhibited.Gail E. Farr, ''Archives and Manuscripts: Exhibits'' (Chicago: Society of American Archivists, 1980), 22. Finally, the exhibition is best protected when equipped with intruder alarms, which can be fitted at entry points to the building and internal areas.
