A water leak at the Louvre Museum in Paris has damaged between 300 and 400 works, mostly books. The leak happened in the Egyptian department and affected volumes used by Egyptologists. "No precious books" were harmed, said Francis Steinbock, deputy administrator of the museum. The problem behind the leak was known for years, but repairs will happen next year. The damaged books will be dried, repaired by a bookbinder, and restored before returning to the shelves. Steinbock described the materials as "Egyptology journals" and "scientific documentation" from the late 19th and early 20th centuries. He assured that "No heritage artefacts have been affected by this damage" and "At this stage, we have no irreparable and definitive losses in these collections." This leak adds to troubles at the world's most-visited museum. In November, a part of a gallery showing Greek vases closed due to structural problems. Earlier in October, thieves stole jewels worth €88 million from the museum during a daylight robbery. These precious jewels remain missing, and some have been moved to the Bank of France for safety. A report by France's public audit body criticized the museum's large spending on buying art "to the detriment of the maintenance and renovation of buildings." The Louvre now faces calls to better protect both its collections and its building.
