If you interested in learning more about antique clocks, go to The Antiquarian Horological Society.
From their website:
The Antiquarian Horological Society (AHS) is a learned society formed in 1953. It exists to encourage the study of all matters relating to the art and history of time measurement, to foster and disseminate original research, and to encourage the preservation of examples of the horological and allied arts. In order to achieve its aims, the AHS hosts meetings, talks and events around the UK and overseas; publishes a range of specialist books as well as a quarterly journal, Antiquarian Horology; and supports education, conservation and historical research through a series of bursaries, prizes and awards. It also runs special-interest groups on wristwatches, electric timekeeping and public clocks.
A website for scholarly articles on furniture &c. would be the Furniture History Society.
