Ideally, focused solely on the technology, not only as it pertains to what is used today but what was used in every era prior to today organized into a timeline of sorts. Alternatively books focusing more specifically on obsolete techology is also welcome. For the former, although I would like information pertaining to it's manufacture and it's purpose in the tech 'ecosystem' at the time, id prefer it not to delve too deeply into the surrounding background history of the invention beyond what is very relevant to it, so basically I'd rather not have the catalogue be interrupted by 10 pages trying to summarize why the societal conditions of belle epoch or the pax whatever facilated this or that which is thought to assist invention; at most a couple sentences talking about it's motivation. Of course, even if a book on the topic violates the above I'd still be grateful if you post it rather than not, simply stating the preference in case one knows multiple of such books.
Similary, I'm curious if anyone's made a torrent with every patent ever published (or of a country in case that hasn't been done).
