A Research lodge is a particular type of Masonic lodge which is devoted to Masonic research. It is a lodge, and as such has a charter from some Grand Lodge. However, it does not confer degrees, and restricts membership to Master Masons of some jurisdiction in amity with the jurisdiction that the Research Lodge is in. Related to Research Lodges are Masonic research societies, which serve the same purpose but function fundamentally differently. There are research lodges in most countries where Freemasonry exists.
The oldest Research Lodge is Quatuor Coronati No. 2076, founded in 1886 under the jurisdiction of the United Grand Lodge of England. It accepts members from all over the world through its Correspondence Circle. A book of transactions called Ars Quatuor Coronatorum (which includes the papers given in the lodge) has been published every year since 1886.
Most Research Lodges have some type of transactions, proceedings, or even just a newsletter that is published regularly.
