Hidden Attachments is a timeline of the small important devices that hold our world together—often overlooked or unseen, but without them, things would fall apart. Many of these attachments have been in use for so long it is impossible to date or locate their invention. The timeline is an approximation and largely western-centric due to sources consulted, such as patent records and English language texts. The representative samples stand in for the concept, rather than being a literal exemplar, especially for attachments from centuries ago. Edition sold out.
