Second: Every time I pass through Alexandria, I try to photocopy as much of Gen. Rif'at al-Jawhari's book "Garden of the Sahara" (1964) as the Library of Alexandria will let me - which is generally not much, since they take copyright very seriously. This important - and hard to obtain - resource for Siwi is now viewable free online in its entirety: جنة الصحراء سيوه أو واحة آمون (Garden of the Desert: Siwa, or the Oasis of Amon). It includes a rather long vocabulary at the end (starting on p. 131) along with a few poems (starting on p. 208). The main text itself is of some interest for its description of Siwi customs, although the author's attitudes are sometimes a bit patronising.
