Referencing dilemma – what to do?

I find it frustrating when in-text references read (Keynes 1973) or (Quesnay 1963). This leaves me to go and find the bibliographical notes to try and discover which works are being referred to and when they were written.  Often the when is significant to understand what is being said by Quesnay, or ‘which’ Keynes is writing – the 1943 Treasury Civil Servant or the young man frustrated with the Versailles Treaty in 1919. If an article then refers to Keynes several times from a ‘collected works’ edition, the time context is almost impossible to decipher as every reference is to 1973 and the reader needs to check page-numbers and chapters to find the original dates. Some authors add extra text before every quote and citation which reads “In year xxx, Dr. yyy wrote”.  I feel this makes the reading slow, tedious and I still have to double-check the years after reading a quote or citation. Such referencing, to me, does not work. But what might be the best practice for referencing translated and re-printed works in the text?

Having checked the brief Harvard guide (that’s the system I’m stuck with) there does not seem to be a rule… There is a rule for translated work in the reference section – using the original year first. Similarly for articles in edited volumes the original date is noted first, with the edited volume’s year of publication later in the reference. From this I infer that the reference in the text would be to the original year and not the edited work. So what do you feel is the best practice?

Let’s take an example: There is a poem by Voltaire written in 1736 entitled Mondrain, translated first by Tobias Smollet [as Man of the World] in 1901 and this translation is re-produced (ad verbatim) in a collected volume by Henry Clark in 2003, which I am using. All this detail is in the full reference at the back. The year of the poem matters to the exposition – as Voltaire will write for another 40+ years, so what do you feel is the best reference in-text? Is it (Voltaire 1738), (Voltaire 1901), (Voltaire 2003) or something fourth, or fifth with square brackets perhaps?
