The document discusses the benefits and challenges of open educational resources (OER). The key benefits are that OER allow students to save money on textbooks, access targeted information both before and after courses, and review materials from a variety of sources. OER also enable peer review of materials and increase the availability of educational content in different formats and from around the world. However, challenges include the time needed to create and curate quality OER, ensuring the accuracy and proper licensing of content, sustaining OER over the long term, and preventing overwhelmed users due to the large volume of available materials.
