In May 2008, Lorenz purchased the Milliken Publishing Company, which had been producing quality supplementary products for over 45 years. Particularly known for its best-selling math and handwriting books, this division includes a complete line of materials that spreads into all major core curriculum areas in a variety of formats. We specialize in blackline reproducible books, workbooks, resource guides, decoratives, and cross-curricular theme units. We also have a diverse line of full-color Transparency/ Reproducible books, which combine color overhead transparencies with accompanying reproducible worksheets.
