This blog, mostly written by Karen Christensen but occasionally by Berkshire staffers, was started at the end of 2004. Over the years, it changed. Some of this informal notes moved to Facebook, Tumblr, Twitter , and perhaps other now-forgotten platforms. Much moved into regular email newsletters. Some of those newsletters were also posted to the blog, conscious as we have always been that online platforms change, and disappear. Karen is mostly to be found on Substack now, and at her own website, KarenChristensen.org. We’re preserving the 2004-2023 record here, and starting a new blog for current Berkshire news, in addition to our mailings for teachers and librarians, at Berkshire Bookworld. Karen’s blog was featured in the Washington Post in 2006: that story is here.
