The primary objective of collection development is to ensure that the library has the resources that its users need to support their educational and research activities.

The popularity of certain resources among users is not a factor to consider when developing a collection development policy, as it can lead to a collection that is biased towards popular resources and does not adequately support the educational and research needs of the institution.

Collection assessment is the process of evaluating the effectiveness of a library's collection in meeting the needs of its users.

Expert opinion is not a method of collection assessment, as it is subjective and may not accurately reflect the needs of the library's users.

Collection selection is the process of selecting resources for acquisition based on the collection development policy and the needs of the library's users.

The availability of the resource in other libraries is not a factor to consider when selecting resources for acquisition, as it does not directly impact the library's ability to meet the needs of its users.

Acquisition is the process of acquiring resources for a library's collection through purchase, gift, or exchange.

Subscription is not a method of acquisition, as it is a method of accessing resources rather than acquiring them.

Collection organization is the process of organizing and maintaining a library's collection in a way that makes it easy for users to find what they need.

Indexing is not a method of collection organization, as it is a method of providing access to resources rather than organizing them.

Access is the process of providing users with the ability to find and use the resources in a library's collection.

Online access is not a method of providing access to a library's collection, as it is a method of accessing resources rather than providing access to them.

Preservation is the process of protecting a library's collection from damage and deterioration.

Digitization is not a method of preservation, as it is a method of creating a digital copy of a resource rather than preserving the original resource.

Preservation assessment is the process of evaluating the effectiveness of a library's preservation program.
