An attentive subscriber kindly pointed out to me that Nabokv-L may not
have previously announced the fact that Dieter E. Zimmer's web site
includes English translations of the two appendices to the German
re-edition of Ada (translated by Uwe Friesel and Dieter E.
Zimmer, published by Rowohlt Verlag in September, 2010).
These can be found here:
http://www.dezimmer.net/ReAda/ReAda.htm
The appendices are "Timeline of Ada" and "The Geography of
Antiterra and Antiterra Gazetteer." Like all of Zimmer's projects,
these are rich and indispensable resources for Nabokov scholars.
