Even when materials are received "shelf ready," what must still be done in the library?

The correct answer highlights the necessity for descriptive cataloging, even when materials arrive "shelf ready." Descriptive cataloging is essential as it creates clear and concise metadata about each item that helps in its identification and retrieval. This process includes providing detailed information such as the title, author, publication date, subjects, and other important details that facilitate user access and understanding of the materials within the library's catalog system.

While marking materials with an ownership stamp, attaching book cards and barcodes, and classifying the materials are all important processes in managing library resources, they focus on physical tracking, circulation, and organization, rather than the creation of a descriptive record that supports user engagement and discovery of the resources. Descriptive cataloging is a foundational element in ensuring that everything in the library system is properly accounted for and accessible to users in an organized manner.
