Welcome to EcoLibrary. Our goal is to help people of all ages, especially teachers and students, learn more about the world in which we live. All of the EcoLibrary materials are available for free download and use, as long as they are used for non-commercial educational purposes. Please do not alter the materials or remove the copyright information when using them.

We are building EcoLibrary in partnership with Discover Life. We recognize that people learn in many different ways and we plan to support different learning styles as we continue to develop materials. EcoLibrary currently contains a database of several hundred images with associated text. In the near future we will add case studies, maps, curriculum ideas, lesson plans, and interactive teaching materials.

Best wishes,

Dan L. Perlman
Founder, EcoLibrary
