Historians at the Auschwitz memorial and high school officials in central Poland are trying to determine how a list of 15 Polish and Jewish inmates of the Nazi death camp made it into a school library book.

A typewritten page, with edges burnt and the word Auschwitz on it, was found inside a book last month during a library stock-taking at the 2nd Lyceum in Lodz.

Auschwitz museum officials said Wednesday they have no doubt it is authentic. Dated May 21, 1941 it bears the names of inmates brought to Auschwitz that day. The same names are on a longer list in the museum's archives.

According to historians, eight of the inmates on the list died in Auschwitz, two survived and the fate of five, including two Jews, remains unknown.
