Circa 2002, I remember printing and binding the PDF 1.4 spec on US Letter paper. It was several 1k's pages of dead trees.
The scary parts were the embedding of JavaScript and arbitrary binary data.

I haven’t had to look at or use the pdf spec in a long time but it might still be valuable to some scanned if it’s not super available.
For 99.99% of the other people in the world that need it, the PDF spec is freely available.
