Title: PROFESSOR ROMAN LEVITSKII'S 60-TH ANNIVERSARY

Very soon, in the year at hand, our colleague Professor Roman Levitskii, Head of Department for Model Spin Systems Theory of the Institute for Condensed Matter Physics, member of the Editorial Board of our journal, will celebrate his 60-th birthday. On this occasion, the Editorial board decided to honour him with a collection of papers, related to the problems of ferroelectric crystals, spin systems theory and other fields of condensed matter physics close to Roman Levitskii's scientific interests and written by people who value him as a prominent scientist. Some of the authors had a great pleasure to collaborate with him during many years of his life in science.
