WS Advance, which is now available to on-line subscribers, was once just for the retailers. If you note the format, they are laid out in a nice easy-to-cut format with guide marks. It appears to me that WS wants retailers to place these as “shelf-talkers” as WS benefits from free advertising. Oddly enough, there are no copyright markings on the sheet (WS editors, take note), nor in the pdf file properties. The WS Insider also does not have any copyright markings (OK, WS editors, REALLY - take note). The printed edition is clearly copyrighted as well as the website, and this includes the numeric score, if you reference WS or the author, BTW.
Many on-line retailers also use the scores and often include the full tasting note quite liberally. IMHO, as for what is posted in this forum, I think it’s crossing the line to post a score or a tasting note on something that is in the current print or electronic issues as this cuts into their sales unless you’ve seen it “advertised” by a retailer.
So, the bottom line is the issue remains quite clouded. But WS does, in the end, hold the copyright and has a right to enforce it.
