Since one of the reasons that many people travel to Jewish sites in central and eastern Europe is to find their family roots and "walk in the foosteps of their ancestors," I'm posting here the link to the archive page of the biweekly online Newsletter, "Nu? What's New?" of Avotaynu, the Jeweish genealogy magazine.
Each issue has a lot of information, tips, links, reports, etc. Much (if not most) fills the specific needs of family historians, but there are also items of general interest to the traveler.
