"The museum, however, continues to be the repository of priceless objects that reflect what the community was and is about. Local museums are also often the recipient of donated artifacts from the community, and while not all of these artifacts may be put on display for various reasons, they remain preserved in the museum’s storage for as long as possible. For this reason, museum curators and owners need to identify and use the right museum shelving for the items in their possession. In addition to keeping everything organized, museum storage units and storage locations have to be selected such that all the artifacts and pieces are preserved and protected from various elements, including heat, humidity, moisture, and physical damage."
