The most recent scholarly materials that I know of are primarily Volodymyr Serhiychuk s books from Kyiv I recently got a copy of published by the Kyiv state University in 2003 He has another interesting book about the Deportation of Poles from Ukraine which was published in 1999 which I used for an article not long ago about Polish deportations I m gradually working my way through the book Another interesting book is Mykola Siwicki s book published in Lviv in 1996 which is also very interesting
