When it comes to efficient use of space, library mobile shelving offers many advantages over static library shelving. The mobile shelving can be moved individually or all at once, meaning that only one aisle needs to be open at any one time. Historically, mobile shelving systems have been used primarily in archive settings. However, an increasing number of academic and public libraries are introducing mobile storage systems into public areas, particularly where there is a requirement to set aside a significant proportion of the library for study, reading and multi-use space.
