Many thanks to Britta Nordström for alerting me to this site.  Business Ukraine (http://biznes-ukraina.ua/) has a useful collection of directories of companies, products and services in Ukraine as well as links to postal codes and transport timetables. There is also a list of  Directories of the world on-line (http://biznes-ukraina.ua/extra.phtml?ttt=1&l=en) that is mostly yellow pages for countries around the world. The market reviews look interesting but the articles are subscription only.

There are Russian, Ukrainian and English language options for many of the sections but you may have to resort to Google’s translation service for some areas of the site.
