In order to mitigate some of the resource implications of collection and description many NBAs also define collecting levels that should be applied for resources, e.g.:
- Comprehensive
- Research
- Instructional support
- General
- Minimal
- Representative sample (this includes criteria stipulating that the NBA collects only a sample of resources of a particular type or format).
