EBSCO has free apps for E-books, Audio books and article searching. However, if you just go through a browser search, EBSCO automatically gives you a mobile view on a smart phone. Tablets usually do not default to the mobile view, but keep you on the desktop view unless you download and use the mobile app.
GALE has free apps for Apple and Android devices for searching their products.
JSTOR will also automatically recognize your mobile device and present a modified format for your screen size.
LexisNexis (for NexisUni) has apps for searching on mobile devices.
SAGE automatically redirects you to a mobile version of their journals and search pages.
ProQuest Ebook Central offers flexible options for downloading content.
Download the book to computers, tablets, and phones. Simply select your device in the first step, and the software will guide you through the rest!

If you’re using a laptop or desktop, you need Adobe Digital Editions a free program that is different than Adobe Reader.
A free Adobe ID is also required to transfer the ebook to another device, but not if you’re just reading it on the same computer.
You can use other reader apps as long as they are able to handle the Adobe DRM (Digital Rights Management). Search in the app store of your choice for e.g. 'adobe drm reader' or just 'adobe drm' to get a list of potentially suitable apps.
Please note: You do need an Adobe ID to be able to read downloaded books on a mobile device. You can get an Adobe ID for free HERE (link goes out to the Adobe account login page where you have to click on the "Get an Adobe ID"-link).
