GORGIAS PRESS has an interesting profile of reprints of Victorian-era and early twentieth-century works on Syriac, Jewish studies, ancient Near East, etc., along with some recent titles on the same. They will also reprint a facsimile of any book you want, as long as it's in the public domain and you're willing to pay the rather steep fee. At conferences I've seen lots of interesting titles on their table, especially reprints of hard-to-find older items.
