Excellent post this!
You may notice that none of the changes all these CEOs were doing sped up the supply chain. Even after Borders put in a reorder for a backlist book, it would still take two to four times as long for that book to make its way back to the store shelf. It could still be weeks after a book sold before the reorder was even placed. There were some efforts made by the sf/fantasy buyer in 2006 to rationalize the sf/f section so that A stores had a full A range selection thus doing away with some of the weird gaps that had developed over the years, but this didn’t help much at the D or E store range to reduce the overall inconsistency of the brand.
