Definition of term:: Wartime paper stock

  • Cheap, highly acidic paper made during World War Two. In order to conserve materials, publishers were encouraged not only to make books smaller, but also to use materials of lesser quality. Consequently these books often deteriorated quickly. After the war publishers in the United States, and particularly the United Kingdom, often had large leftover stocks of this material, so these cheap materials can be found used sporadically in books published for approximately ten years after the war.
