Museum display cases are usually one of the most expensive parts in museum interior design andfurniture; museum display cases are very special and have a lot of limitations in the selection ofused materials. Usually, even the micrometer environment in museum shelves and display casesshould be valuable in the primary control of a collection (۱). The protected manuscripts inmuseums are particularly vulnerable in terms of vulnerability and difficulty in maintaining. Themechanisms of damage and preventive protection of these works and their changes over timedepend entirely on environmental conditions (۲). Display cases, as a means of protection, protectthe works by increasing the security of the objects and confining them in an appropriate, stable andsecure environment (۳ and ۴). In general, four main groups of factors cause damage to themanuscripts: ۱- Physical factors ۲- Chemical factors ۳- Biological factors ۴- Unexpected factors(۵), each of which imposes specific requirements in the design and manufacture of display cases forprotection. Due to the specific circumstances of these works, these requirements need to becollected and formulated in a purposeful way for the design of the display cases. This article hasattempted to clarify what features each display case must have in order to be stable and to protect amanuscript by reviewing specialized texts, authoritative articles, and library resources. Finally, anexample of an appropriate design based on the stated conditions is examined.
