The "Diapositive" web site in Poland has undergone a make-over since the last time I looked at it. It has a useful English language section with a lot of information and links on contemporary Jewish life in Poland, as well as on Jewish heritage sites, resources and events.
Run by the Adam Mickiewicz Institute, the site used to carry the full text of Adam Dylewski's Jewish guidebook to Poland,"When the Tailor Was a Poet" -- but now it presents the material (and more) in its "Traces of the Past" section.
Its starting map looks similar to the map that starts the POLIN portal of the Foundation for the Preservation of Jewish Hertiage in Poland, but I'm not sure if there's any direct link or cooperation.
