Most online full texts are available in PDF format (Portable Document Format). You need the Adobe Acrobat Reader to display the format properly. However, you will still find a lot of full texts in HTML-format, so that you will also need an up-to-date web browser.
On some platforms, e-books are provided for reading offline with the software “Adobe Digital Editions”. To download and save the e-book, you need to install “Adobe Digital Editions” on your computer or tablet and the “Adobe Digital Editions” app on your smartphone. This copy protection software ensures that e-books cannot be handed on illicitly to third parties, and are only accessible on your device for the period of the “loan” to you.
