By the numbers
What is in the archive
Every total this site can measure, in one place: the books and recordings themselves, how much text and running time they add up to, how large the download is, and where the record is still incomplete. Each figure is counted from the catalog when the site is built.

- 944

How these numbers are made
Every figure is computed when the site is generated, by counting the catalog and the files it points at, so the page cannot drift away from what the archive actually holds.
For where the collection came from, see About the archive; for the generator, agent workflow, and build gates behind these figures, see How this site is built; for the machine-readable rights table, see licenses.json.
The companion The Austrian Economics Wiki holds the reference layer: see Special:Statistics for its article, edit, and page counts.
