I want to cite some things for a proposal for school. I own the PD by Wiseman and Ye in hardback, and I obtained it on Pleco as well. I noticed that the Pleco entry for the dictionary says it has "corrections + new entries for this Pleco edition," but I cannot find that information (such as the year). At the expense of sounding unlearned, should I just cite the hardback version (third edition, 2014) that I have? Or do I instead just cite Pleco?
