One way to reduce costs for students is to assign readings from content held by PSU Library. Most of PSU's journal holdings are in electronic format, allowing you to link to articles you want to assign. Information about identifying persistent links to articles is available here. If the desired content is part of the Library's print holdings, an article or a book chapter can be scanned and made available through the Library's e-reserves system. Search the Library catalog to make sure we have the article, chapter, etc. and place it on ereserve.
PSU Library subscribes to a wealth of online materials you may wish to incorporate into your course assignments. When you search the Library catalog you can filter your results for eBooks, Streaming Audio, or PSU Online Sources to find these.
Another way to find eBooks that may be to browse through some of the eBook collections the Library holds.
