The news that hundreds of copies of Anne Frank's "A Diary of a Young Girl" and books about her had been vandalized in libraries across Tokyo has continued to spur widespread concern, with some people now scrambling to help repair the damage with generous donations.

More than 300 cases of such vandalism had been reported as of Wednesday, including in Suginami, Nakano, Nerima and Shinjuku wards, according to media reports. Pages of "A Diary of a Young Girl" and the other books were ripped out or slashed with a knife.

The police are investigating.
