The Complete Starfleet Library is cited as a source in the German book Faszinierend!Star Trek und die Wissenschaften Band 2, or, in English, Fascinating! Star Trek and the Sciences Volume 2.
I'm glad I don't read German, in a way, because there are so many Star Trek nonfiction books published in German that I might otherwise feel the need to buy. Buying books from amazon.de is easy enough, but the shipping costs are a bit much (yes, I've actually looked into this). But still, I'm intrigued by books like Star Trek in Deutschland: Wie Captain Kirk nach Deutschland kam, Jenseits der Sterne: Gemeinschaft und Identität in Fankulturen. Zur Konstitution des Star Trek-Fandoms, and especially Science and a Sense of Hope - Zum Verhältnis von Wissenschaft und Religion in der Fernsehserie Star Trek: Deep Space Nine. (Drifting a little, there's also those six Space: 1999 novels only published in German, two of which I own but can't yet read. Maybe someday.)
It's disappointing to go from Amazon.de, with its large number of translated novels and comics and original German nonfiction, to Amazon.fr, which has very little Trek material in French. Few novels have been translated in recent years, and original nonfiction about Trek in French seems to be all but nonexistent -- a shame, because I'd be able to read it with a pretty good degree of comprehension. Searching for Patrouille du Cosmos, the title under which I sometimes saw it at my grandparents' in Quebec, didn't help. Turns out that was the Quebec title; according to French wikipedia, France didn't get Star Trek until 1982 and kept the English title.
Anyway, here's the cite (from Google Books):
Yes, I am geeky enough to think it's cool that my site's been cited in a book.
