Serious readers organize, convert, edit, and serve their e-book libraries with Calibre - the definitive open-source e-book manager. This deployment runs the full Calibre desktop application on your server, accessible from any browser, so your library lives in one authoritative place instead of scattered across devices. Its conversion engine is the best in the business, translating between every major format - EPUB, MOBI, AZW3, PDF, DOCX, and dozens more - with fine control over fonts, margins, metadata, and structure detection. Metadata management downloads covers, descriptions, series info, and identifiers from online sources, and every field is editable in bulk. Beyond cataloging, Calibre includes a full e-book editor for EPUB and AZW3 internals, a news engine that fetches newspapers and magazines from the web on schedule and converts them into e-books, book comparison tools, and device syncing that sends the right format to each connected reader. The built-in content server exposes your library over HTTP so phones, tablets, and e-readers can browse and download remotely. A deep plugin ecosystem extends everything - metadata sources, format support, store integrations. For power users, the complete CLI (calibredb, ebook-convert) enables scripted library automation. Your books, your metadata, your server - permanent and DRM-free storage under your control.

A folder of loose audiobook chapters goes in; a single, perfectly tagged m4b library comes out. Bragibooks is the operations board for that transformation: you select a batch of audiobook folders from your server, and it searches AudiobookDB to match each one with the right title, author, narrator, and release, with a custom search on hand when the first match is wrong. Confirmed books enter a processing queue where m4b-merge merges split mp3, m4a, and m4b parts, converts formats, strips stale metadata, and writes clean, consistently tagged files while you watch the live job output in your browser. Saved output profiles let you route different batches to different directories or path formats, and the books library keeps every finished title with its metadata, files, and processing history a click away. The whole thing runs as one container with the interface built in, a SQLite database on a mounted config volume, and access restricted to your local network by default, with an optional API key for external tools. Audiobook collectors use it to tame download folders before importing into their player of choice, and hoarders of split-chapter rips finally get uniform Chapter 01 style files.

Circulation desk, cataloging workbench, acquisitions office, serials room, and public catalog all share one roof in Koha, an open-source library system that scales across school libraries, branch networks, and consortia. Staff search the catalog with facets for availability, authors, holding libraries, and item types, then open a record to see its cover, subjects, classification numbers, and every copy with its call number, status, and barcode. Catalogers edit MARC 21 or UNIMARC records field by field, copy records in via Z39.50 and SRU searches, and link authorities automatically. At the desk, staff check out, check in, and renew items, work with holds, bookings, and claims, and see overdue warnings and outstanding charges beside each patron. Circulation and fine rules vary by library, patron category, and item type. Acquisitions handles vendors, baskets, budgets, and funds. Serials track subscriptions and issue receiving. A guided report wizard, SQL reports, and statistics wizards summarize circulation and collections. Patrons search the public catalog, place holds, save lists, tag and rate titles, and suggest purchases. Staff tools design notices and slips, print patron cards, set holiday calendars, and import or batch-edit patrons. SIP2 serves self-checkout kiosks, OAI-PMH sets share records, and a REST API exposes patrons, holds, checkouts, and biblios. Lending continues during outages with offline circulation.

Shelfarr is the request button your book library was missing: anyone in your household can search millions of ebooks and audiobooks, request the format they want, and let automation fetch and shelve it. Discovery searches Open Library, Hardcover, and Google Books with covers, series, editions, and narrator details, so picking between the ebook and the audiobook takes a glance. Hardcover shelves and public reading lists can be previewed and requested, and following an author means their next release surfaces without a manual search. Requests wait for an admin's approval or move straight to searching, where your indexers are queried and every result is scored against your preferred formats, bitrate, and language. The winning release goes to the download client you route it to; finished files are renamed with your templates and delivered into your library's watched folders, which are told to rescan. Nothing found is not the end: searches retry with back-off and flag the request for attention instead of losing it. Family members get their own accounts with roles, two-factor authentication or single sign-on, notifications in the app or on Discord and Telegram, and admins keep manual uploads, API tokens, and download routing under their control.

Your want-to-read shelf and your audiobook library finally talk to each other, so the next book you finish can trigger the hunt for the one after it. Dewarr syncs Goodreads shelves, CSV exports, custom public lists, and Hardcover lists, then watches them for new additions worth listening to. Connect Audiobookshelf or Grimmory and it knows what you already own, importing finished downloads into verified library folders instead of leaving files stranded in a downloads directory. Follow authors and series to catch future releases, with back-catalog review, filters, and exclusions before anything is grabbed, including release-day acquisition for titles you are waiting on. When you approve auto-download, it searches MyAnonamouse, Prowlarr, and AudiobookBay, ranks sources by your format, size, and seed preferences, and hands transfers to qBittorrent. Multi-file MP3 releases come back as one chapterized M4B, a chapter per file, ready for your player. The discovery page personalizes shelves with followed lists, award collections, trending books, and new releases. Household members get individual accounts, reading lists, and permissions, with sign-in through OpenID Connect providers or Plex. Notifications for grabs, imports, and digests go out over Discord, ntfy, Apprise, or plain webhooks.

Radarr, Sonarr, and their sibling apps watch RSS feeds for new releases but never go back for what your library is still missing, and Houndarr fills that gap by asking them to search in small, polite batches. It reads the wanted lists of every connected Radarr, Sonarr, Lidarr, Readarr, and Whisparr instance and sends a few search commands per cycle, so a big backlog drains over days instead of arriving as one Search All Missing burst. Each instance has its own batch size, sleep interval, hourly cap, per-item cooldown, and post-release grace period, plus an optional download-queue limit, allowed search windows such as 09:00-23:00, and tag filters that include or exclude items. Three independent passes run per instance: missing items, cutoff-unmet items below your quality profile, and upgrades for files that already meet cutoff, with the last two off until you enable them. Sonarr, Lidarr, and Readarr can search by season, artist, or author, and search order is random or oldest-first. The dashboard shows library health, recent hunts, hourly budgets, and a cooldown schedule per instance, with Run Now buttons for on-demand cycles. The Logs page records every search and skip with its reason in a filterable audit trail that copies as TSV. A key-gated widget endpoint feeds Homepage dashboards, and built-in login or reverse-proxy authentication protects the interface.
