Retail sales in December rose only 0.4 percent after seasonal adjustment, the Commerce Department reported.

President Franklin D. Roosevelt used a secret device to record news conferences in the Oval Office of the White House for 11 weeks during his 1940 re-election campaign, according to a history professor who has spent the last three years studying the recordings. Some private conversations were also recorded, apparently inadvertently. The recordings, which have been stored at the Franklin D. Roosevelt Library at Hyde Park, N.Y., for more than 30 years, total about eight hours of material, most of it from the 14 press conferences held in the Oval Office between Aug. 23 and Nov. 8, 1940. In the recordings of private conversations, President Roosevelt commented on a wide range of subjects. He cited the American public's readiness ''to pull the trigger if the Japs do anything'' and complained on another occasion about the ''fascist'' propaganda techniques of Wendell L. Willkie, a Republican contender for the Presidency.

The 5-to-3 decision said that the city of Boulder, Colo., could be sued by a cable television company that charged that the city's regulatory policies were favoring a competing company and restraining trade in violation of the Sherman Antitrust Act. The Justices reversed a decision by the United States Court of Appeals for the 10th Circuit, which found that the city's cable television policy was immune from antitrust challenge.

But after the first set was built he threw everything out. Although he could not explain exactly what he wanted, he felt it was all wrong, and he told the set designer, Melvin Bourne, to start over. What Mr. Bourne finally created for Mr. Allen was a spare but elegant interior using not Italian modern furniture nor 18th-century English antiques but the ''poor man's furniture'' of Britain - stripped pine.

It hit the bridge with a deafening roar and then, suddenly, there was silence. There was no sound at all, those who watched said later, as the Air Florida 737 jetliner glided onto the river, skidded across the gray ice and sank slowly into the icy waters. Behind it, a 10-wheel truck, its top sheared off, teetered on the bridge over the Potomac River. Half a dozen cars, their trunks and hoods crushed, were strewn across the roadway. And through a 35-foot gash in the bridge railing only a slender piece of the crushed airliner was visible.
