I'm writing a master thesis where part of the source material is from conversations with employees and is not necessarily written anywhere. What would be the best way to cite this?
I am considering using @misc and just have title="Information from <3-4 people in the company>" and then cite to this whenever I feel it is needed in the paper. Another solution could be to use the preface to thank for the help and explain that some of the information is taken directly from them. However, I feel this is not accurate enough.
Of course I could try and ask them for written information about it, but I fear this would take too much time, since the deadline is not that far away.
