The Brooklyn Collection of Brooklyn Public Library supports its activities partly through the sale of rights and reproductions of high resolution images for commercial use. This income is used for the purchase, conservation and preservation of materials, and for library programs focusing on Brooklyn history. The watermark discourages unauthorized use of our materials. Also, it is important to us that you should know where these images come from. Low resolution images disseminated through the web advertise our collections, and for those wishing to obtain a high resolution copy, the watermark designates which institution.
