I wonder about copyright dates of books.
How long does it take from the time research is conducted and validated to the time it is published, consumed and utilized?
So if in June of 2017 I read something that indicates Copyright 2016 - is it fair to assume that it was published 6 to 17months ago?
Would it be beneficial if the copyright date included the month and not just the year?
And if the research took a year to conduct to account for seasonal effects is it fair to add another 6 months to the age of the information? And how long did it take to analyze the research, validate the conclusions and get the manuscripts approved? It was not likely overnight. I suspect that 3 months would be considered remarkable and that 9 months might be a better estimate.This could likely add another year to the age of the information.
So now, in June of 2017, the book with Copyright 2016 is likely to have information that is 18 to 29 months old. What has changed in the last 2 years?
