So back in the day, I edited and published Outremer, an anthology of prose, verse and drama on the Rudel legend by the likes of Robert Browning, Heinrich Heine, PG Wodehouse, AE Swinburne and Edmond Rostand. You can order copies of the book from me, or from Amazon marketplace (also me, effectively).
I've also put up a website with some - but not all - of the material featured in the book, along with some of the beautiful illustrations by Marcus Sedgwick.
(Update June 2012: The website's gone for the moment - I don't like the look of the whole MobileMe-to-iCloud palaver, so I've unsubscribed.)
Feel free to email me for more info on the book.
