Downloading full versions of EBSCO and eBook Central eBooks requires the free Adobe Digital Editions software, which is available for both Mac and Windows here: https://www.adobe.com/solutions/ebook/digital-editions.html.

Instructions for downloading and installing Adobe Digital Editions can be found here: http://support.ebsco.com/knowledge_base/detail.php?id=5882

If you are trying to view the eBook on a mobile iOS or Android device, you'll need to download the free BlueFire Reader app.

Both EBSCO and eBook Central allow you to download individual chapters of eBooks in PDF format, which does not require additional software. More information about that process can be found here: https://library.drake.edu/get-help/faqs/use-ebsco-e-books/
