從 Kobo Store 購物時，如何確定某本書是否受DRM影響？還要確定使用哪種DRM？
I.E., there is an italian publisher called Newton & Compton that
uses a watermark social DRM. For example, if you take the Sherlock
Holmes Omnibus on their
site, under the tab
informazioni aggiuntive it is
protected with watermark; on bookrepublic,
another italian store,
the same book is labelled as
protected with Social
DRM (the same thing as watermark); but on Kobo Books, I
can't see the DRM specifications anywhere
on the page.
Is it possible to determine in some way what kind of protection
have the books when shopping from Kobo Store without having to rely
on other stores or publisher's sites?
And I am correct to assume that Kobo uses the same DRM restrictions of the original publisher (i.e. watermark for Newton & Compton and DRM-free for LiberLiber)? Or does it apply its own kind, without any notice to the end user?
