Some of my references are annual publications of which I'm using multiple editions. I cannot figure out, however, how to cite them with only 1 reference entry. In the text it should look something like this:
And in the References:
IEA 1996-2012. Energy Balances of non-OECD Countries, Paris.
BibTex does not seem to accept year-ranges in the year field...
Any help is highly appreciated!
