How to Use Circulation Data for K-12 Library Collection Development

What Using Circulation Data for K-12 Library Collection Development Includes
Collection development using circulation data is the practice of combining checkout activity with collection details, curriculum priorities, enrollment, and professional judgment to decide what a K-12 library should purchase, retain, relocate, or remove. Circulation data shows how often materials are being used, but it does not explain every reason a title may be popular or overlooked.
In a school district, collection development is usually shared by school librarians, a district library director, curriculum leaders, and administrators responsible for budgets and equitable access. The work includes reviewing usage by title, subject, grade level, format, school, and time period. It also requires checking publication date, condition, relevance, duplication, curriculum alignment, and whether students can discover the material.
Circulation is therefore a decision input, not an automatic purchasing or weeding rule.
At a glance
- Circulation data identifies patterns of use by title, subject, format, grade level, and school.
- Low circulation is a review signal, not proof that a title should be removed.
- Purchasing decisions should combine usage trends with curriculum priorities, collection gaps, condition, and student access.
- District-level comparisons can reveal uneven collection age, availability, or usage across schools.
- A documented review process makes collection and budget decisions easier to explain to administrators.
Use circulation data as one part of a repeatable collection review process. Start by examining circulation over a defined period and group the results by school, subject, grade band, format, and publication year. Look for patterns rather than reacting to one title or one unusual month. A title that circulates frequently may indicate demand, while a subject with consistently low use may require further investigation before any materials are removed.
For purchasing, compare circulation patterns with curriculum priorities, enrollment, reading interests, and known collection gaps. High demand can support additional copies, newer editions, or related titles. Low circulation can indicate limited relevance, poor discoverability, insufficient promotion, an outdated topic, or a collection that does not match student needs. Review those possibilities before deciding what to buy.
For weeding, use circulation to identify candidates for review. Then check condition, accuracy, currency, representation, duplication, local importance, and curriculum value. A title with no recent checkouts may still support instruction, represent an important perspective, or be needed in a small school with limited alternatives.
Districts should document the criteria used, the date range reviewed, and the final decision. This creates a clear record for librarians and administrators and helps maintain consistent practices across schools. Library reporting tools, including reporting in Follett Destiny Library Manager, can support this process when the underlying catalog and circulation data are maintained consistently.
District Library Director
A district library director compares circulation by subject across elementary schools before setting the next purchasing priorities. The review shows where demand is high and where schools have fewer current resources, which informs a district discussion with curriculum leaders.
School Librarian
A middle school librarian reviews three years of title-level circulation before a summer weeding project. They use the report to create a review list, then check condition, accuracy, curriculum relevance, and representation before removing or retaining materials.
Curriculum Director
A curriculum director and district administrator review collection and circulation patterns during budget planning. They use the evidence to distinguish requests for replacement copies, new subject coverage, additional copies, and materials needed for instructional priorities.
Decision Points
Common Questions
What time period should be reviewed?
Use a consistent period that reflects the decision being made. A full school year may support annual planning, while a shorter period may be useful for a targeted subject or program review.
Should low-circulation titles be weeded automatically?
No. Low use should trigger review, followed by checks for condition, currency, curriculum value, representation, and local need.
How should a district compare schools fairly?
Use comparable measures and account for enrollment, grade span, access policies, collection size, and differences in programming or scheduling.
When should circulation lead to purchasing more copies?
Consider additional copies when demand is sustained, holds or waitlists are common, and the title supports current student or instructional needs.

From Data to Discovery: How Follett Software AI Gives Librarians More Time to Engage and Advocate
When people think of school librarians, they often picture someone checking books in and out – but the role goes far beyond that. Librarians manage collections, support teachers and curriculum, foster a love of reading across diverse grade and skill levels, and create engaging learning environments. On top of that, they must continuously advocate for resources, often through time-consuming reports. But with only so many hours in the day, balancing it all is a challenge.
Shannon needed a way to efficiently track library usage, support data-driven decisions, and communicate the library’s impact to administrators, teachers, and students. As a dedicated Follett Software Library Manager user, Shannon needed a tool that could deliver quick, accurate insights while reducing manual effort.

Practical Guidance
Define the decision before pulling data.
Specify whether the review is for annual purchasing, subject-area gaps, additional copies, a weeding project, or a budget presentation.
Set consistent review fields.
Include circulation count, last circulation date, publication year, condition, subject, grade band, format, school, and enrollment where relevant.
Create review lists, not automatic actions.
Use high-use titles to investigate demand and low-use titles to investigate possible weeding or discoverability issues. Require professional review before changing a collection.
Record the rationale.
Note the report period, criteria, reviewer, decision, and follow-up action so the process can be repeated and explained across the district. Follett Destiny Library Manager reporting can support this workflow when district data is maintained consistently.

FAQ
-
It shows which titles, subjects, formats, and grade levels are being used. Librarians can combine those patterns with curriculum priorities, enrollment, condition, and collection gaps to determine where additional or different materials are needed.
-
It may be a candidate for review, but circulation alone is not enough. Check accuracy, condition, curriculum relevance, representation, local importance, and whether students can find or access the title.
-
Many districts review data as part of annual purchasing and collection planning, with additional reviews for targeted subjects or weeding projects. The most important practice is to use a consistent schedule and documented criteria.
-
Yes, when the comparison accounts for enrollment, grade span, collection size, access policies, and programming differences. Cross-school review can reveal uneven access or collection needs that are not visible in a single-building report.
-
Useful context includes publication year, condition, subject coverage, curriculum alignment, enrollment, holds or requests, format, and availability by school. Student and educator feedback can also explain why a title is or is not being used.
-
Circulation can document one aspect of resource use, but it does not measure the full value of a library program. Pair it with evidence about access, collaboration, reading activity, instructional support, and progress toward district goals.
Summary
Circulation data helps K-12 library teams make collection decisions based on observable use, but it should be interpreted with professional judgment and local context. A documented process that combines usage, collection health, curriculum needs, and equitable access produces clearer purchasing and weeding decisions.
