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.

How it breaks down
The same catalog, sliced the way the filter menus on the books, courses and authors indexes slice it. Each bar is the row's share of the largest row on its card.
Books by subject
Subjects are tags, not shelves: a book carries up to three, so these add up to more than the catalogue.
Books by length
Books by era
Books by format
A book with several editions counts once per format.
Recordings by kind
Authors by era
By birth year, or death year less 65 where only that is known.
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. Ratios always carry their denominator, and a figure the build could not measure is left off rather than printed as zero.
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.
