The document discusses the Marrakesh Treaty, which aims to improve access to published works for visually impaired persons. It notes that producing accessible formats of books is difficult and expensive. The treaty addresses this by allowing authorized entities to produce and share accessible format copies across borders. It also protects technical measures and the privacy of beneficiaries. The treaty was adopted in 2013 in Marrakesh and will take effect once 20 countries have ratified it. The document urges libraries and organizations to support countries signing and implementing the treaty.
