Can anyone assist? From the email I originally received, I suspect that English is not the student's first language. So if you know of good materials written other than English, please mention them too.
"I am currently doing an academic research on the subject of Intangible Assets Valuation. I could find a lot of information regarding this subject, but I barely found any information related to Copyright Valuation. The only article that I found was in Willamette website: http://www.intellectualpropertyanalysis.com/article3.html
Could you tell me if there is more bibliography on this particular subject? I would be very appreciative. Thank you in advance".
