I feel I have a reasonable sense of the contribution made by the French Annales school in the interwar period and its postwar reception but am certainly not an expert. As such I find it very hard to recommend an introduction for people who are unfamiliar with it - "type 'Annales' into JSTOR and read the first hundred results" seems unreasonably burdensome. If you had to recommend either a single monograph or no more than three articles to introduce someone to the history, impact, and key insights of the Annales school what would they be? And to make it trickier, since I know who I usually have to recommend things to, without recommending anything in French.
