There are also very old carriage makers catalogs buried in there.
But, the search tools on archive are **awfull**
The good news, google has some of that stuff indexed, so sometimes you turn it up via google, if you craft te search just right.

Hint: Use the web book reader, if you like the catalog, download the PDF, most of them are searchable.
