Charles Halpin has been named senior v-p in charge of the R.R. Bowker and Cahners book publishing group, which includes PW. Halpin, currently managing director of the professional and banking division of Reed Business Information in the U.K., will begin his new job in January and will be based in Bowker's New Jersey headquarters. With Halpin's appointment, Bowker-Saur in the U.K. will become part of Cahners and will report to Halpin.

Halpin will report to Glenn Rogers, executive v-p of entertainment, communications and media group of Cahners Business Information. Rogers noted that while Bowker and the book publishing group are being placed under Halpin, they will remain separate entities. Brewster Jackson, acting head of Bowker since the departure of Neal Goff, has been put in charge of overseeing the development of the Digital Object Identifier.
