One of the main reason of cooperation collection development is to redress library shelf space constraints?

Yes, that is one of the reasons for cooperation in collection development. By collaborating with other libraries, institutions can share resources and avoid duplicating materials, which can help alleviate shelf space constraints. This allows libraries to provide a wider range of materials to their patrons without having to physically store all of them on site. Additionally, cooperation in collection development can also lead to cost savings and increased access to specialized materials that may not be feasible for individual libraries to acquire on their own.
