Inserting references that are Whitepapers. Not really a common practice in thesis papers - but I had one that was released by Autodesk on Stereoscopic 3D as when I wrote my lit review at the time I found it difficult to find a good 'technical' look at how S3D works.
To reference it in my LyX document, I'm using the application JabRef (available for download here)
So to reference it, add a new entry then select "TechReport"
Once that is selected fill in the fields as required. In my instance, I had left the bibtextkey blank, so make sure that is filled in. Once it is, its easy enough to go Insert > Citation and select the bibtexkey and done!
