In the past, some of the main review journals directed their reviews toward professionals--librarians, for the most part, who were looking for information on books they might want to add to their collections. That's why some reviews included what most of us would consider spoilers. The reviews didn't spoil the books for the librarians, who couldn't possibly read all the books they needed to know about, anyway, but did give them information that helped them make purchasing decisions.
Library Journal has announced a change in its review policy. "The librarian-centric focus no longer makes sense in an electronic environment where our reviews appear in online catalogs and other resources that patrons use to find titles, place holds or make purchases, or even add their own comments. In the last few issues of LJ, we've begun to direct our assessment mainly toward the reader."
They've also introduced "a self-contained "Verdict" at the end of the review that sends the reader right to the reviewer's opinion." This "Verdict" aspect of the reviews, the Library Journal review editors believe, will make reviews more '"twitterable."' (To quote their quotation mark-emphasized word.)
So...how long has Twitter been around? Is it really so well established in our culture that it's time to be designing other media around it?
