VELIKY NOVGOROD, Russia — The note, from father to son, was the sort of routine shopping list that today would be dashed off on a smartphone. In 14th century Russia, it was etched into the bark of a birch tree and curled into a scroll.

“Send me a shirt, towel, trousers, reins, and, for my sister, send fabric,” the father, whose name was Onus, wrote to his son, Danilo, the block letters of Old Novgorod language, a precursor to Russian, neatly carved into the wood with a stylus. Onus ended with a bit of humor. “If I am alive,” he wrote, “I will pay for it.”

The scroll and a dozen others like it were among the finds from this year’s digging season, adding to a collection of more than 1,000 birch-bark documents uncovered here after being preserved for hundreds of years in the magical mud that makes this city one of the most extraordinary archaeological sites on earth. “Novgorod for Russia is like Pompeii for Italy,” said Pyotr G. Gaidukov, the deputy director of the Russian Academy of Sciences Institute of Archaeology. “Only Novgorod is still alive.”

Written in conversational language, on everyday topics, the birch-bark documents provide a remarkable human soundtrack to accompany a vast — and still growing — trove of artifacts including coins, official seals, kitchenware, jewelry and clothing. Each year, thousands of items are found amid buildings and streets, once paved with wooden logs, buried in the soil.
