Part of the charter of the Lewis Carroll Society of North America (LCSNA) is to publish materials relevant to Lewis Carroll studies. The Society maintains an active publication program including new Carroll studies, primary material, and a Society magazine.
The Knight Letter is the name of the Society’s magazine. It contains scholarly essays, entertainments, illustrations, and plenty of news items. Generally running about 50 pages per issue, it appears twice per year and is present at major libraries and is on various databases. Some far-flung folks who cannot join us at meetings retain active memberships purely based on their enjoyment of the Knight Letter.
These books published by the LCSNA are available for sale. They are a significant resource for Carroll studies. And they’re good reading, too!
