How Does Equipment Affect Aerial Photography Costs? 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. Instead, photo corners, polyethylene, or polyester film straps may hold the object to the support. 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. It even includes a committed support team to handle your questions or doubts. The long term idea was that per­haps it could maybe be an exhi­bi­tion or maybe even a book down the road. 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. Outgassing from materials used in the construction of the exhibition case and/or fabrics used for lining the case can be destructive.

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. All these objects can be arranged simultaneously in one horizontal case under a unified theme. Then it is that a doubtful balance is made between truth and pleasure, and that the knowledge of the one and the feeling of the other stir up a combat the success of which is very uncertain, since, in order to judge of it, it would be necessary to know all that passes in the innermost spirit of the man, of which the man himself is scarcely ever conscious. Several small objects can be combined to balance one larger object. But with prices still extremely low, real estate can be a good investment opportunity. Using internal buffers and pollutant absorbers, such as silica gel, activated carbon, or zeolite, is a good way to control relative humidity and pollutants. The most common way to display bound materials is closed and lying horizontally. 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.

Light wavelength, intensity, and duration contribute collectively to the rate of material degradation in exhibitions. It is recommended that high-quality facsimiles of especially delicate or fragile materials be displayed in lieu of originals for longer exhibitions. Library or archival materials are usually displayed in display cases or frames. New cases may be preferred, constructed of safe materials such as metal, plexiglass, or some sealed woods. Objects in frames should be separated from harmful materials through matting, glazing, and backing layers. Backing layers of archival cardboard should be thick enough to protect objects. For example, pilots flying into San Francisco's airport must often deal with thick banks of fog. UV radiation must be eliminated to the extent it is physically possible; it is recommended that light with a wavelength below 400 nm (ultraviolet radiation) be limited to no more than 75 microwatts per lumen at 10 to 100 lux. Artificial light sources are safer options for exhibition. 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. An items level of toleration will depend on the inks or pigments being exposed and the duration of the exhibition time.

As all objects in the library exhibition are unique and to some extent vulnerable, it is essential that they be displayed with care. Thorough crowd management is essential to prevent such tragedies. Objects may also be encapsulated in polyester film, though old and untreated acidic papers should be professionally deacidified before encapsulation. Unbound materials, usually single-sheet items, need to be attached securely to the mounts, unless matted or encapsulated. The control of relative humidity is especially critical for vellum and parchment materials, which are extremely sensitive to changes in relative humidity and may contract violently and unevenly if displayed in too dry an environment. Cases provide a physically and chemically secure environment. 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. 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. Furthermore, exposure to natural light is undesirable because of its intensity and high UV content. The intensity of visible light in the display space should be low enough to avoid object deterioration, but bright enough for viewing.
