Overseas readers especially should act now. To cover costs of shipping the Law and History Review overseas, members outside of North America must add $10 to their membership fee. The price is going up however: "We regret that beginning on January 1, 2009, individuals and institutions resident outside of North America will need to add $25 (rather than $10) to these prices to cover overseas shipping of the journal." More info on that is here.
(By the way, when visiting the membership sign-up page, please disregard a paragraph that thanks you "for your interest in LERA membership." LERA is the Labor and Employment Relations Association, and the paragraph is a typo, to be corrected at some point.)
So pick up a stocking stuffer for your favorite grad student, or treat yourself to membership so that you, too, can be a legal historian!
