The author describes how the concept of collection, reflecting the profession’s principles, values, and practices as they pertained to print-based (analog) information resources, developed in the pre-World Wide Web environment. She poses five questions related to goals and practices in the analog environment to help libraries develop a concept of the hybrid collection.
