Can you move multiple TOC entries at once?

icearch — Sun, 24 May 2026 02:37:07 GMT

I've editing some garbage auto generate epubs, they tend to have single layer of TOC which is hard to navigate. So I change them.

But here is the thing, it seems that you can't select multiple entries in Editing TOC window, making it hard to edit.

So am I doing it wrong or Sigil just can't do that? Currently I'm directly editing nav or ncx, which is annoying and tend to need several tries to make it correct.

Summer of '84 - A perfect summer read!

timber987 — Sat, 23 May 2026 23:35:46 GMT

My book Summer of '84 is a perfect read for the summer months. You can find it here:

https://www.amazon.com/Summer-84-Edw...s%2C212&sr=1-2

Forty years ago, an eleven year old boy went missing, never to be seen again. Only a small gang of boys know the truth of what happened that day. Now, Bobbie, tells what happened that summer day in 1984. A story filled with with adventure, thrills and horror. It is a story you won't soon forget.

cool pdf conversion footer

rjwse@aol.com — Sat, 23 May 2026 11:34:45 GMT

Instead of just left/right on odd/even pages this is outside/center on odd/even pages. The trick is to make a fake div with spaces for the unseen third inside margin element. This alternates _TOP_LEVEL_SECTION_ (Part 1) with _SECTION_ (chapter number)

Rename file name with variables

icearch — Sat, 23 May 2026 05:17:27 GMT

Is there any plugins or built-in functions to bulk rename xhtml file names with variables?

Say like after some editing, I'm end up with bunch of xhtmls with random file names, and now I want to rename them to chapter-a-01, chapter-a-02... and so on, how do I do it is sigil?

I know there is regex rename files, but it seems can't generate variables? At least I don't know how to do it.

Please Help Errors While Adding

Atuin! — Sat, 23 May 2026 05:05:17 GMT

Hello, I am trying very hard to transfer my ebooks to my new Kobo, but every time I put any of them into Calibre I get an error message saying the following

Calibre won't start on Mac

jazzhands — Fri, 22 May 2026 20:59:31 GMT

I haven't opened Calibre for about a week and now it seems to not be able to open up on my mac. I attached the most recent error report that was produced from the force quit. This is happening with version 9.8 and 9.7. My first attempt was just rolling back to the previous version, but that didn't work.

Any suggestions would be appreciated.
Attachment 223482

Sorry the report is zipped. It's just a text file inside, but it was too big to attach originally.

Kindle scribe, 2022 edition connected to wi fi icon, except in book setting menu.

solitarywolf — Fri, 22 May 2026 19:05:51 GMT

I recently noticed the WiFi symbol on the pull down menu above reading a book does not appear.

In any other screen the symbol is there. It�s always connected and working. Just the symbol is missing.

I reached out to Amazon. They had me do the 40 second reset. I have also used the setting menu to �restart� my kindle. I am running the most recent os, 5.19.4.0.1.

Other than the missing icon, the kindle behaves as expected. No issues there.

Anyone else seeing this or have an answer?

Can't Find Typed Word, But Finds Pasted Word

enuddleyarbl — Fri, 22 May 2026 18:57:27 GMT

All of a sudden, I'm having trouble searching for words in the editor in one particular book. If I type in a word to search for (any word), it won't find it. If I copy a word and paste it in the search bar, it finds it. I keep staring at the screen trying to see what I'm doing wrong (including spelling), but don't see anything.

Here's a screenshot of my latest attempt (the cursor is one line above that word I'm searching for). It finds nothing. Here's the error message:

Code:

calibre, version 9.8.0

ERROR: Not found: No matches were found for 
im*por*tant

Those asterisks and the pre-style stuff don't show up in the actual error message. I assume they're just for display purposed in the Editor. Maybe the asterisks are soft-hyphens for some reason?

EDIT: I've gone so far as to reboot the computer and try again. Still doesn't work. I can search fine in other books.

EDIT2: This is even weirder than I thought. I proceeded to search for other things, and the searches worked. I tried the search I showed here ("important") and it didn't find any instances of that word. Copy/Pasting it again lets it find all instances. If I search for other words in that sentence, it finds some, but not others. For instance (going down the sentence) "Shut up", "he", "told", "them" all work. But, the next word in the sentence ("quietly") does not.

[GUI Plugin] CleanRead

JHAT — Fri, 22 May 2026 18:08:11 GMT

CleanRead � Calibre Plugin v1.0
Author: JHAT
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
DESCRIPTION:

CleanRead sanitizes EPUB files for a cleaner reading experience.

Two independent options can be applied separately or together:

▸ Language Filter:
Replaces strong profanity with context-aware substitutions �
handling compound words, dialect forms, verb uses, and idiomatic
phrases � while preserving the author's voice and narrative tone.

▸ Clean & Strip:
Removes injected watermarks, promotional links, piracy metadata,
Calibre-specific OPF artifacts, and forced CSS background colors
left behind by conversion tools.

The original EPUB is never lost. The cleaned file keeps the original
filename (.epub) and the untouched original is automatically archived
alongside it as .ORIGINAL_EPUB. Both formats are registered in your
Calibre library so you can access either at any time.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
INSTALLATION

1. Download CleanRead_v1.0.0.zip (attached below)
2. In Calibre: Preferences → Plugins → Load plugin from file

eBooks on Amazon downloadable as ePub

JSWolf — Fri, 22 May 2026 15:55:06 GMT

Let's start a list of eBooks on Amazon that can be downloaded as ePub. That way if anyone wants to buy any of these eBooks, they'll know they can be easily downloaded and read wherever you prefer.

How do I ignore a device?

brab — Fri, 22 May 2026 13:52:36 GMT

I would like to be able to plugin my Kobo Clara to USB without Calibre recognizing it (because it then prevents me from using �Connect to Folder�, which I want to do to access my koreader library). I found there is a list of ignored devices, but I cannot find how to add a device to it. Is it possible to do it?

(For context, I typically connect koreader on the Clara to Calibre using wifi, but sometimes I do not have access to wifi and I would still like to be able to use USB to transfer books. I know I can do it manually (by just opening the book folder and copying it to the mounted file system), but I prefer Calibre interface for this.)

NEW THREAD!!! - What is this person holding?

Dr. Drib — Fri, 22 May 2026 11:47:47 GMT

I searched the internet and could find no clues. And frankly, after my extensive search, I'm flummoxed. The object appears to be exerting a strange force on the man's lower lip, as if attempting to (perhaps?) ingest his bodily fluids. If so, the object seems too small to contain a summation of fluids.

Anyone who can help me identify this object will get a hearty handclasp. (The hand will be mailed in a special container to prevent deterioration.)

Do you have any strange stories of someone holding something that makes no sense whatsoever or is in some way dangerous to humanity?

Please understand that this thread is ONLY for people with a high degree of intelligence. If you post here, then I will naturally assume that you are gifted with intelligence and you know it! Why? Because you made the decision to post here! If you do NOT make a post in this thread, then that speaks volumes for your lack of...well...HOWEVER, do not despair. I have it on good authority that there is a Politics and Religion Forum where those less 'gifted' than the rest of us can make posts all day and all night long! AND, it is only about one inch away from this Forum.

:D
