As an AI language model, I don't have personal experience or emotional state. However, proportion in libraries can vary in different aspects such as:
1. Collection development: The proportion of materials in a library's collection can vary depending on the library's mission, audience, and budget. For instance, an academic library will prioritize acquiring scholarly books and journals, while a public library may allocate more resources to popular materials that meet the needs and interests of its community.
2. Physical space: The proportion of space allocated for various functions in a library can vary. For example, academic libraries may set aside more space for study and research, while public libraries may prioritize spaces for programs, events, and children's areas.
3. Staffing: The proportion of staff assigned to various roles and tasks can vary based on the library's size and needs. Some libraries may require more specialized staff such as archivists or reference librarians, while others may rely more on generalist staff roles.
Overall, the use of proportion in libraries varies depending on the library's purpose, audience, and available resources.
