Reconstruction talk:Proto-Slavic/kory

Source?
Where is the source? I found *kory in "Etymological Dictionary of the Slavic Inherited Lexicon". Which is correct or are both correct, if so where is a source or any kind of reference? 5.43.190.207 03:24, 27 December 2013 (UTC)
 * *kory is the original form, *korenь is analogical. --Ivan Štambuk (talk) 18:26, 27 October 2014 (UTC)
