Some ebook platforms will require you to download a browser plugin or ereader software if you want to download an entire ebook onto your PC, laptop or mobile device. It is advised that you have installed Digital Rights Management software such as Adobe Reader and Adobe Digital Editions on your PC or laptop, as both of these can be required to download ebooks offered as PDFs. If you want to download entire ePub format or PDF ebooks to your iPad, tablet or smart phone then you will need to install an ereader app such as Bluefire Reader (available for Android, iOS and Windows devices).
If you want to download an entire medical etextbook hosted on Elsevier’s eLibrary platform you will need to install iPublishCentral Reader and download Adobe Air. Android and Apple iPublishCentral Reader apps are available from the Google Store/App Store.
