The original source of the story seems to be 30,000 books attacked by fungus in the National Library:

The National Library has been bursting at the seems for a long time and books had been temporarily stocked in the basement but humidity rose unexpectedly and damaged over 30,000 books.

Most of the posts I have seen are all the same and seem to pretty much use the text from this article verbatim. Interestingly, the website of The National Library of Luxembourg doesn’t have anything to say about it.

Many common molds such as species of  Acremonium, Alternaria, Aspergillus, Cladosporium, Fusarium, and Penicillium can grow on paper products.

If all else fails, contaminated documents can be blasted with gamma radiation to kill the fungi while leaving the paper intact. Harvard Magazine published an article on preventing loss of books from fungal attack early last year. Another article is Emergency Salvage of Moldy Books and Paper.
