# Items

Our item data includes millions of items held by all 7 library services. We are splitting out these exports into one file per service, to make them more manageable. Plus, because we use GitHub for storage, there is a 100Mb file limit!

## Summary file

A summary file includes counts of items, aggregated by item type, and library service. In this case we have one summary file for all services.
