Translated Edtions of STM Journals

[Norman Frankel <publishing2@hotmail.com>]

I am looking for hard data that show the impact of translated
international editions of US based English language STM journals
on direct paid subscription sales of these English language
editions. Does the translated edition cannibalize direct paid
sales of the English language edition?  Or does it make the pie
bigger and increase paid subscription sales?  As far as anyone
knows, is there any hard data that proves this, one way or the
other?  I am thinking that the clinicians are more likely to read
the translated edition while the researcher will be more likely
to read the English version.

But I never remember seeing any hard data.

Thanks,
