How to Organize an Audiobook Library (Audiobookshelf, Plex)

The short answer

Library servers build your shelves from folders and tags. Put every book in its own folder, inside its author folder, with a series folder in between when there is one.^1,5 Audiobookshelf also reads the book number, year and narrator from the folder name, like Vol 1 - 1994 - Title {Narrator}.¹ Then tag the files: Plex and Jellyfin take most details from the tags, and Audiobookshelf uses them too.^2,5,6

Rule one: One folder per book
Layout: Author / Series / Book
Narrator: In {braces} or the composer tag
Then: Tag the files

  Ender's Game.m4b

From Audiobookshelf’s own documentation: books are folders; single-file books may sit at the library root, but “every book must be in its own folder.” The author folder can hold “First Last” or “Last, First”, and several authors separated by commas, “&” or “and”.¹

Jellyfin wants books organised by type (Audiobooks), optionally by author, “each book in their own folder”, and reads an audiobook’s details from its embedded tags.⁵ For Plex, see below.

Author names aren’t punctuation-aware: “J.R.R. Tolkien” and “J. R. R. Tolkien” become two authors, so pick one spelling.¹

The tags that matter

Folder names are only one source. Audiobookshelf’s scanner reads the tags of the first audio file (after sorting by disc and track). Its default order of precedence, highest first: its own metadata file, an OPF file, desc.txt and reader.txt, an NFO file, the audio tags, and the folder names last.²

Tags Audiobookshelf reads (the first one found wins)
	Tags it reads	Our editor writes
Author	artist, album artist	artist and album artist
Title	album, title	title and album
Narrator	composer	composer
Series	series, show, mvnm	show (M4B), series (MP3)
Book number	series-part, episode_id, mvin, part	episode_id (M4B), series-part (MP3)
Year, description, genre	year, description, genre	all three

It also reads side files in the book folder: desc.txt for the description, reader.txt for the narrator, an OPF file (as Calibre writes) and an NFO file. It uses an image in the folder for the cover, and only extracts the embedded one if there isn’t one.^1,2,3 Our metadata editor’s library download includes the cover, desc.txt and reader.txt for you.

Plex

Plex has no official audiobook support. The common community setup is a separate library of the Music type for audiobooks, with “store playback progress” turned on for that library only, and careful tags, because the album artist and the folder structure decide how Plex groups books.⁶ Community guides go further, with metadata agents and an audiobook app on top.⁷ An app such as Prologue gives Plex audiobooks proper chapters, speed and a sleep timer.⁸

Fixing a messy library

Merge scattered parts into one file per book
A folder of 40 MP3s works, but one M4B with chapters is easier to move, tag and play. The MP3 to M4B maker does it in the browser.
Tag each book
Title, author, narrator, series and book number, year, cover. For a folder of MP3s, tag them all at once and number the tracks.
File it in the right folders
Download from the metadata editor as a library folder and unzip it into your library, or create the folders by hand as above.
Rescan
In Audiobookshelf, scan the library. If books were grouped wrongly, remove the merged item and rescan.

Everything else, answered.

How should I organise audiobook folders?

One folder per book, inside a folder for the author, with a series folder in between for books in a series: Author/Series/Book. Audiobookshelf reads all three from the names; Jellyfin wants each book in its own folder under the author; Plex relies mostly on the files’ tags.

How do I name an audiobook folder for Audiobookshelf?

Like “Vol 1 - 1994 - Wizards First Rule {Sam Tsoutsouvas}”: the book number after “Vol”, the year, the title, and the narrator in curly braces. Each part is optional, and they are separated by “ - ” with spaces.

Why does Audiobookshelf show several books as one?

Usually an audio file sits in a folder that also contains other book folders, for example a loose MP3 in the author folder. Every book must be in its own folder (or be a single file at the library root). Move the file into its own folder, remove the merged book in Audiobookshelf, and rescan; progress for that book is lost.

Which tags does Audiobookshelf read?

Author from artist or album artist, title from album or title, narrator from composer, series from series, show or mvnm, the book number from series-part, episode_id, mvin or part, plus year, description, genre, publisher and language.

Does Plex support audiobooks?

Not officially. The usual community setup is a separate Music library for audiobooks with playback progress stored, files tagged carefully (album artist and album matter), and an audiobook app such as Prologue to play them.

Should each chapter be a separate file?

It doesn’t have to be. Audiobookshelf plays a folder of files as one book, in disc and track order, and understands Disc 1 or CD 2 sub-folders; one M4B with chapters is tidier still, and works everywhere.

Where does the cover go?

Embed it in the files, and put an image in the book folder as well: Audiobookshelf uses an image file in the folder first, and Jellyfin looks for images named cover, folder or poster.

Do I need to rename all my files?

No. Folder names and tags do the work; file names inside a book folder only need to sort in order (01, 02… or Track 1, Track 2), or carry track numbers in their tags.
