Addendum to my paper "Some short historical notes on development of mathematical logic in Sofia''

The above-mentioned paper, published in Ann. Sof. Univ., Fac. Math. Inf., 96, 2004, 11-21, presents a talk given at the Conference on Mathematical Logic and its Applications, Gyulechitsa, December 14-16, 2002. It was expected that the volume would contain some general information about the conference, and the information would mention, in particular, the fact in question. Therefore no indication to the fact was included in the paper itself, but, unfortunately, the expected general information did not appear in the volume.
