Today's Hours
Open Educational Resources are free, open access teaching, learning, and research resources that can be freely used or reused by others, including full courses, course materials, modules, textbooks, streaming videos, tests, software, and grading rubrics. CCNY Libraries' Digital Scholarship Services links to background readings and some OER examples at CUNY here.
Zero textbook cost (ZTC) courses are those which use a combination of OER as well as subscription-based CCNY Libraries databases. Students already contribute to the cost of databases through their tuition, so they will not have to spend extra money on these resources.

The following databases are not open access; they are subscription databases available to the CCNY Libraries community. However, since they are already included by assigning readings from these databases, students will not have to pay any additional fees. A course may be designated a ZTC (zero textbook cost) course if the required readings are composed of open access and/or readings available through our subscription databases since students will not have to pay anything extra to access the latter.
