The Broad Street branches, which include speciality music and art/poster shops, remained the only ones until expansion in the early 1990s, when at peak after taking over Heffers in Cambridge in 1999 and James Thin in Scotland in 2002, the company had over 70 outlets. Its library supply chain serves an international market, but parts were sold off in 2009, with the North American arm of Blackwell Book Services and the Australian business James Bennett sold to Baker & Taylor for their academic arm YBP Library Services. The group were also publishers, under the Blackwell publishing imprint which published over 800 journals when it was sold to John Wiley & Sons in 2007 for £572 million to form Wiley-Blackwell.
