From Béla Lipták:
As to ISA, I will not be able to make it this year. Between October 19 and November 7 I will be in Hungary for the 50th anniversary of our fight for freedom.
(I wrote a book about thet, which was published by Texas A&M University Press with the Title: "A Testament of Revolution".)
Best regards, Béla
PS: On this old photo, which shows how the revolution started, I am the second on the left of the first row.
