How to Add Sufficient Velocity Stories to Calibre

To add a Sufficient Velocity story to calibre, first download it as an EPUB with WP Downloader. You can then import, organize, convert, read, or transfer the book in calibre. WP Downloader is a free web tool, so you do not need to install anything.

Download the Sufficient Velocity story

Sufficient Velocity stories are published as forum threads. WP Downloader gathers a thread’s threadmarked chapters and puts them into one book.

A story link usually looks like this:

https://forums.sufficientvelocity.com/threads/some-story-name.123456/

To download a story:

1. Open the Sufficient Velocity downloader.
2. Paste the story thread URL into the box.
3. Choose EPUB as the output format.
4. Choose whether to include the story’s images.
5. Download the finished file to your device.

EPUB downloads are free for everyone. PDF is also available with a free Discord sign-in. EPUB is a practical choice for calibre because the app can read, organize, and convert it.

WP Downloader downloads the whole story, not individual chapters or lists. It collects the threadmarked chapters for you, so you do not have to save each forum post separately.

You can sign in with your Sufficient Velocity account to reach members-only stories that the account can read. Signing in is optional for public stories. WP Downloader uses your account credentials only to fetch the story you request, and it cannot bypass locked content, age restrictions, or other access controls.

See the Sufficient Velocity download guide for more help with downloading a story.

Add the EPUB to your calibre library

calibre is a free e-book manager for Windows, macOS, and Linux. Once the EPUB and calibre are on your computer:

1. Open calibre.
2. Select Add books.
3. Find the EPUB you downloaded from WP Downloader.
4. Select the file and add it to your library.

The story will appear with the other books in your library. Select it to read it in calibre’s e-book viewer.

The viewer also has a Read aloud feature, which lets you listen to the book without changing the EPUB.

Edit the story details and cover

After importing the story, you can edit its metadata and cover in calibre. This can help you keep names, covers, and other details consistent across a large fanfiction library.

Select the book and open calibre’s metadata editor. Review the information attached to the EPUB, make any changes you want, and replace the cover if needed.

A consistent naming system can make stories easier to find. It also helps to check the book’s details whenever you import a newly downloaded copy.

WP Downloader cannot update an existing EPUB when new chapters appear. Download the story again to get the latest threadmarked chapters, then add the new file to calibre. Check which copy is current before keeping or removing either one.

Convert the story for another device

WP Downloader creates EPUB and PDF files. It does not create MOBI, AZW3, or TXT files.

If your reading device or app needs another format, calibre can convert the EPUB. Select the story, open calibre’s conversion tool, and choose an available format such as AZW3, MOBI, or PDF.

You may want to keep the original EPUB in your library as a source file for later conversions.

Kindle readers can follow the guide to send Sufficient Velocity stories to Kindle. Kobo readers can see how to read Sufficient Velocity stories on Kobo.

Transfer the story over USB

calibre can send books to an e-reader connected to your computer over USB.

Connect the reader and wait for calibre to recognize it. Select the imported story, then use calibre’s device transfer option to send it to the reader. If the device needs a different file type, convert the EPUB before transferring it.

You can also read the EPUB in calibre’s e-book viewer. Once the book is saved to your calibre library or e-reader, it is available for offline reading.
