Joe Reynolds, who took over as president of Scholastic Library Publishing division in March, has resigned. A company spokesperson said Reynolds's departure was for personal and family reasons. Greg Worrell, who most recently served as senior v-p of sales and marketing for Scholastic's education group, has been named to succeed Reynolds. Unlike Reynolds, who had reported directly to Scholastic chairman Dick Robinson, Worrell will report to Margery Mayer, president of the Scholastic education group.
