The ebook format is so important because of its reflowable nature. “Reflowable” means that the text will rearrange itself to fit your screen size. If you increase or decrease the font size, the text also rearranges itself. This is hugely different from standard page displays like those in PDF files. On those files, if you wish to increase the text size, all you can really do is zoom in on the page. EReaders try to let you increase the font size but it always affects the page size as well, cutting off the edges of the pages.

If you zoom too far in, you have to scroll sideways back and forth in order to read the a whole line of text. This is the main reason why I think ePub is the best ebook format, and I hope it stays around for a long time. And because of that, I wanted to compile a list of the best current ePub reading programs that you can use on your computer. Most eReaders can display ePubs, and you can use them on your Android or iOS device (with programs like and, for example), but not everyone knows which program to use to open them on your computer. DRM If you’re going to buy an ePub file that is protected by Adobe’s DRM, you’ll have to use. Likewise, if you buy an ePub ebook at any specific website that has their own DRM, you’ll probably have to use the software that they recommend, but that depends on the website so I can’t tell you what you need. Non-DRM For regular ePub files, you have some choices: – You can still use Adobe Digital Editions for non-DRM ePubs.

I do because I already have it installed on my computer. – This is a program that lets you create, organize, and read your ebooks. – A Firefox addon that allows you to read ePubs directly in Firefox. – Works on Linux/Unix and Windows. – Bought by Amazon a while ago, and seems to be slowly shutting down.

Still good for now. There are others available that you can dig up, but these listed above are the ones that I feel are best.

Stanza, for example, can read many ebook formats but ignores a lot of formatting so you end up missing out on the intended design of the book. Rememberthemilk sync with outlook for mac. Because of that I suspect that other readers might do the same thing. I think that we’ll probably see more programs released as more and more people use the ePub ebook format.

Even now I am seeing that ePub and PDF are the most popular (Kindle notwithstanding) and since ePub works best on the widest range of devices, it is the clear winner as far as I am concerned. Adobe Digital Editions is a free program created by Adobe for use with PDF and EPUB ebooks that are protected by Adobe’s DRM. Part of my work involves providing some technical support for users who encounter errors from this program. Since I don’t work directly for Adobe, I’ve had to develop my own solutions to these errors.

This particular error is frustrating for ebook users because the error doesn’t give any hints as to what the problem actually is. The full text of error message is similar to this (depending on your computer): IOError on local file open Path: (this varies depending on the folder names in your computer) Event Detail: Error #2038 — end — Over time I’ve been able to identify three possible solutions to this error. Sometimes none of these three will solve it for a user, but these options take care of the majority of cases.
