The journal of the German Society for the Exploration of Palestine – ZDPV – is now also available online via JSTOR. Note, however, that there is a “moving wall” of three years. At present, access is limited to institutions only.
Please inquire at your local library if access is provided. The ZDPV is part of JSTOR’s “Arts & Science Collection IX”.
Free access to ZDPV 1-30 (1878-1906) is provided by www.archive.org.
