Ukraine Records that are available on line can be found on Alex Krakovski's Ukraine wiki page at https://uk.wikisource.org/wiki/%D0%90%D1%80%D1%85%D1%96%D0%B2:%D0%84%D0%B2%D1%80%D0%B5%D0%B9%D1%81%D1%8C%D0%BA%D0%B5_%D0%BC%D1%96%D1%81%D1%82%D0%B5%D1%87%D0%BA%D0%BE.  The page is in Ukrainian but the Chrome browser will allow you to view a reasonable translation to any language you like.  The scans themselves, are in cursive Cyrillic (and some in cursive Hebrew, as well). Steve Morse has a one-step that helps you find names and critical words on his pages at www.stevemorse.org.  

Bear in mind the Ukraine Research Divison only has information on towns in the area of eastern Ukraine that were part of the Russian Empire in 1914.  Other town information is available from Gesher Galicia, Sub-Carpathian Research Division, and Bessarabia Research Division.  For a more complete list of records known to exist, check Miriam Weiner's excellent site at rtrfoundation.org.  Click on the box that says Archive Douments.  For best results, use the D-M Soundex search for the town you are researching.  

Finally, due to the current situation in Ukraine, researchers are, for the most part, unable to do any current research  there.  We have no current informtion on the state of the current archives in Ukraine, but you can assume they are all subject to war damage.  We do know Russian rockets destroyed a bulding adjacent to the Mykolaev Archives and caused damage to that building.
