Which department is primarily responsible for obtaining materials through purchase, gift, or exchange?

### Why this is right The acquisitions function builds the collection by obtaining materials. Common methods include purchase, gift, and exchange. ### The concept Acquisition and cataloguing are different stages of collection work. Acquisition obtains resources; cataloguing creates records that describe and provide access to them. ### The other options - **Reference department**: It helps users with information inquiries rather than primarily obtaining stock. - **Circulation department**: It manages lending and returns. - **Readers' services desk**: It supports user services but is not the unit named for collection acquisition. ### Remember Purchase, gift, and exchange point to acquisitions.
