THE NEW EDITION OF BROCKELMAN'S LEXICON SYRIACUM, edited by Michael Sokoloff and published by Gorgias press, has now produced a pdf document with corrections to first printing and orthographic variants. I noted the first printing of the Sokoloff edition in 2009 here. The current advert for the book is here.
This is an excellent way of circulating errata lists for complex works such as lexicons.
