I've just converted a PDF to epub in calibre but because the PDF has two columns of text on each page the ouput epub is essentially 'combing' all the lines ton the PDF's page together, making the epub very hard to read.

How do I make Calibre feed one column at a time from each page into the conversion?

Hope that makes sense and thanks!

So I just started using calibre on my tablet pc. I have an issue where any italicized text is put in a block with a background the same color of the body. I'm assuming this has a greater z-index so it blocks the text above and below any italicized text.

I have installed the opens-dyslexic font and am using it and it really does help. Even if it looks a little comic sans like. Pretty sure its not the font causing this and its a bg color being applied to the italicized text with a greater z-index than the body at least that what it looks like. I have used CSS since its adoption but I really hate it! I don't do any real work with it anymore.

So I was wondering if there was a general easy way to download styles and hopefully apply them to all books? It would really suck to have to find issues in css and fix them per book just to be able to read.

First book was styled nicely. Maybe there wasn't any italic in the text though.

Sorry for the long title. Some context to this: Readium LCP is a DRM-solution created and delivered by the non-profit foundation EDRLab (I guess we've learned by now that non-profit doesn't equal good), based in France.

EDRLab is an international, non-profit development laboratory working on the deployment of an open, interoperable and accessible digital publishing ecosystem worldwide.

In recent years they've gained a large market share in the EU first and foremost, providing both regular e-book shops in many EU countries and libraries with this DRM (if you're intereste

Hi, is there any way to sync devices directly to Calibre server? I would like to keep the database on a server and sync directly from there. This would allow to leave out syncinc the library to a laptop first. Thanks for your support!

I manage my ebooks locally and then upload them to my calibre-web container via the webui. It's there an easier way to do this? I no longer use a shared backend storage for fear of corruption/loss so i was looking for an easier way (export plug-in?). Any one have any ideas?

I use the page count plugin plus a template program I adapted from one found online (included below) to build a column that categorizes books by length. (I use this to build collections I use when I’m picking my next to read)

I’d like to exclude certain books from getting a classification though if they are PDFs or have tags like “Graphic Novel” or “Cookbook”. I’d appreciate any help figuring this out.

I frequently use Calibre to convert academic papers from PDF to epub, so I can read them on my tablet. But the conversion often results in weird formatting artifacts.

I'm aware that in the Conversion tool, there's a Search & Replace section, where I can list various expressions that will help me remove things like page numbers. This post has some helpful expressions for that. For example:

\d+<br>\n|\d+\w<br>\n|\w\d+<br>\n

Does anyone have a list of more expressions that they use when converting academic papers from PDF to epub? Especially any good expressions for handling footnotes?? I would love to get a bunch together, save them, and then simply load them every time I have to do this.

Thanks all!

A bit of a long shot, but I guess it doesn't hurt asking.

I'm using Calibre with the library on a network share (I'm aware this is not recommended, however I'm using this for years without any problems on Windows and Mac OS). Recently I gave Linux another shot and I stumbled upon a problem with accessing my network share.

When trying to add this library which is sitting on the network share, the Calibre file explorer doesn't show the network locations I added in Dolphin in the "Remote" tab. Is there any way to convince Calibre to find these network locations without adding the shares in /etc/fstab?

Edited meta in Calibre doesn't stick with the epub file. Is there any method to edit dc: meta in epub and the designated series under series shows up in Calibre?

Thanks and trying my best to explain the concept. If this is to vague please provide guide to explain more specific.

I have my calibre synced from pc to Nextcloud and use the android app to link them together.

I mostly read reference books - recipes, photography, history - so I don't need, or have the space to keep the books on my mobile phone.

This works great however, what I'd really like to do is read my books without having to download them first.

I guess I'm looking for a lazy approach to reading my reference books without storing them all on my phone.

Anyone have any different approaches that I can learn from?

Hi! Does anybody know how to change the format of the dates to YYYY-MM-DD?

Thanks!

I have 3 different libraries, one for comics, one for TTRPG books, and my main one for actual eBooks. My main library is over 4GB with over 1,000 books.

No, I haven't read all of them, but I am working on it. They have been collected over the last 15 years from Sony eReader store, Kobo books, Amazon Kindle, B&N, Archive.org and other Public Domain books hosts, Humble Bundle, Story Bundle, and various other places.

Largest categories are Sci-Fi, Fantasy, and Mystery.

I wish there was a way to link to an Android app.
