The Wall Street Journal will debut a newly formatted version of its print edition starting Nov. 14, which will combine several sections and reduce the size of some coverage areas as the paper copes with an accelerating industrywide decline in print advertising.

Editor in chief Gerard Baker announced the changes to staff in a memo Wednesday. As a result, the paper will feature fewer pages with less space dedicated to coverage of arts, culture and New York news.

"All newspapers face structural challenges and we must move to create a print edition that can stand on a sound financial footing for the foreseeable future while our digital horizons continue to expand," Mr. Baker wrote in the memo.
