Calibre (http://calibre-ebook.com/download) is a free multi-platform reader that will not only help you manage these eBook files, but will also enable them to be read on a PC in Windows, Mac or Linux formats. (If you find calibre useful, then please consider making a contribution)
A simple milti-platform reader (Platforms: Win32, Linux, Android) is CoolReaderhttp://sourceforge.net/projects/crengine/files/ This is small and fast.
Both the Chrome and Firefox web browsers have ePub reader plug-ins available, so you can use your browser to read our publications.
Note that Apple products (iPad, iPhone etc) come supplied with a very good ePub reader called iBooks.
Ken, W6HHC, reports that he obtains best reading of CQ-DATV on an iPad or iPhone using the iBook ePub reader app in the "scroll mode". Although the iBooks user manual never mentions it, there is a "scroll" mode buried under the "font settings icon" in iBooks reader. Open the icon - select "themes" - select the "slide" setting.
