ok. with due respect i would not want to pay more for a DEVONthink license to help pay for the capital and support costs DEVON Technologies would bear to provide this. Especially since reading Epub books stored in DEVONthink can already be read with a reader of your choice. Just my two bits, as they say.
As to Koreader: they are extracting the text from m the PDF and then reformatting that. As long as there is a text layer, you could do that even in DT. But that has nothing to do with the PDF as such (imagine a carefully laid out text flowing around images, in two columns).
Well, that's at a very high level, and doesn't help us much. You can break down step 1 by reading up on the epub format itself (e.g.: wikipedia article and general info). Pretty quickly, you should notice that the format uses OCF to package together multiple files, so your first problem will be to create an OCF reader, which also means that you will need to be able to unzip the data in javascript (Florian Margaine's links should give you an idea of how others have solved this problem). At this point, I'd start looking for existing implementations in javascript, because you probably don't want to be implementing all of this from the ground up. This is all before we're even touching the actual contents of the epub file. Once you are past this point, you should be able to read in the actual contents, and attempt to translate them into HTML.
Regarding step 2, I'd start by looking at the various features provided by epub - text, CSS styling, embedded images, etc - and start attacking those one at a time, starting with whatever gives the most return for my time (probably text...).
TreineticEpubReader is a popular fork of readium-js-viewer it provides a very simple api to interact with epub files, you can load either the epub as .epub or serve the extracted folder path of the epub
Hi. Your current process with PDFs just relies on the fact that an Evernote attachment can be opened by any suitable editor, and the amended version saved back to the note. No special 'integration' required. If you can find some specialist epub software with an editor that allows you to highlight text and save back to an epub file, that should be enough. Some web searching and research required though, I think - please let us know if you find a good epub editor.
You could also look into whether highlights transfer when an edited PDF file is converted to an epub file. Calibre is certainly capable of converting the epub file to PDF and back. It also has some epub editing features. Calibre has an inbuilt library folder, but it also edits epubs. It could be useful to try it out.
Just did a bit more research, it seems that epub files don't support any annotation functionality within themselves. Its the e-reader software that creates that ability, but the annotations never get stored in-file. Which means that, at least for now, I'll have to content myself with exporting highlights as an external file and plonking those into Evernote.
Or converting the epub files to PDF... but then I'll run into another issue, which is whether annotated PDFs will automatically be saved back into Evernote when I'm on a tablet. I'll probably have to manually reupload the changed file every time I'm done reading.
Phew! But nah, I won't make a feature request to Evernote as I'm sure they'll just ignore it. If its taken 7 years of people wanting different highlighter colours and its still not happened, then I doubt they'll add epub reading capabilities any time soon.
Another useful option, try this in Firefox; -US/firefox/addon/45281/, a fairly good extension for the Firefox web browser that lets you read .epubs from the browser, especially good since on Ubuntu you are likely to be using Firefox and it is usually kept open when you are using your computer.
lucidor at does a decent job. I completely removed calibre from my system because it doesn't let me leave the books in my own directory structure. (Then spent hours moving the thousands of books into a directory structure I like by hand.) I couldn't find coolreader to try. Okular I like but the extensions did not work on epub for me. fbreader works but you have to open it up first and then the book whereas lucidor you can right click from the file manager to associate epubs to lucidor.
I read math textbooks. This requires constant shifting back and forward to specific places in the book via internal hyperlinks, bookmarks and (sub)chapter headings. The focus that I really need is navigability, and I'm surprised how little of it is implemented in epub readers. I usually read pdf, but I would like to read them as epub (or similarly reflowable format) and I have some books already as epub.
I know there are a lot of readers available and to so far I've tested Calibre (fails #7, barely #6), Icecream (fails #2) and Freda (fails #2, barely #4,#7) don't do all of the above. Kindle, Kobo and Vitalsource don't seem to do #8. Is there an epub reader that will do all of this?
I imagine a system where the reader application would allow you to read, highlight, and annotate sections of a book and save all of the relevant data (including links to the exact section) to a single text file per book.
I think this is a better idea than trying to force logseq into being an epub reader on top of being a note taking app. There are plenty of epub reader application developers we could reach out to if this is the direction the community decided to go.
I just installed the add-on epub-Reader. To open an epub-file its mandatory to have the toolbar-button of this add-on - but this button didn't appear in the FF-toolbar. Even de-install and re-install the add-on didn't change this problem nor the FF-start in private mode.
I have signed up for Flightdeck and ran the EPUB file through that. It came up with some Validation errors. I have no idea how to fix them though and don't know if those errors would contribute to the reader problems
Thank you for your comment Bob. Yes, it does seem odd that a file created and exported with an Adobe program does not read well on an Adobe reading app. I'm afraid I'm a newbie with InDesign, although I'm familiar with other Adobe programs such as Photoshop, Premiere, Audition, Encore. Are the problems I'm experiencing with the epub in ADE mostly a result of ADE's shortcomings or are there things I should be doing prior to export that could alleviate the problems? Thanks again.

I'm looking for a ePub reader to read a collection of .epub files I have but so far each one I've tried has had problems because I don't have an SD card in my phone or I haven't been able to figured out how to get it to read a file that I uploaded to the device.
Accessibility is an essential benefit EPUBs offer to users: the format has the capacity to support many features that ensure all users will be able to enjoy the e-books. EPUBs are compatible with screen reader technology and they allow for alt text for images in the e-book. The table of contents in an EPUB can serve as a navigation aid and structured metadata helps with navigation as well as discoverability. The 2017 EPUB Accessibility specification from IPDF outlines requirements for EPUBs to conform to accessibility standards. While not all EPUBs conform to these specifications, many publishers and creators are designing their EPUB e-books with these provisions in mind.
Lilygo and M5 are the easiest options to start with since the hardware part is already solved. The benefit of M5 EPD is that it comes with an SD Card reader. Is possible also to upload the ePub books in the SPIFFs section of the ESP32 but there is limited space.
Epub files are a bit of a pain to parse. Despite the file extension epub, they are actually zip archives containing multiple files. To read the file I'm using a nice zip library from here: lbernstrone/miniz. This library has been modified to work...
EPUB is an e-book file format that uses the ".epub" file extension. The term is short for electronic publication and is sometimes styled ePub. EPUB is supported by many e-readers, and compatible software is available for most smartphones, tablets, and computers. EPUB is a technical standard published by the International Digital Publishing Forum (IDPF). It became an official standard of the IDPF in September 2007, superseding the older Open eBook (OEB) standard.[2]
