“Dispersal was a conscious strategy of the plunderers. Only by destroying these collections could they build up new ones. Many of these libraries were the results of decades, sometimes centuries, of careful collecting. There had been generations of learned collectors and readers. The books also said something about the people who owned and treasured them: what they read and what they thought and what they dreamed. Sometimes they left traces in the form of underlined passages, notations, notes in the margins, or short comments. The beautiful and personally designed ex librises that many readers had made for their books demonstrate the care and pride they took in their libraries. Each collection in its own right took form in a unique culture, a depiction of its creator's world, which was lost when the library was broken up. The books are fragments of a library, of a world that once existed.”

“The extermination of Poland's literary heritage was frighteningly efficient. Researchers have estimated that 70 percent of all books in Poland were destroyed or lost through plunder. Over 90 percent of collections belonging to public libraries or schools were lost or destroyed.”
