The workflow: Convert → Read → Sync → Library
Most people assemble an ebook collection by accident. A purchase here, a PDF from a course there, a folder of classics downloaded one rainy evening, three devices holding three different subsets. No single file is wrong, yet the collection is unusable: you cannot answer "do I own this?" without opening four apps.
A library is what you get when four stages run as a loop instead of one-off chores:
- Convert. Books arrive in whatever container the seller chose. One format decision up front removes a hundred compatibility problems later.
- Read. Progress, highlights, notes and ratings are created here, and that data is as much your library as the files.
- Sync. A library on one machine is a library you use in one room.
- Library. Cataloguing, status and backup are the parts everyone skips and later wishes they had not.
The nine sections below follow that loop: an afternoon for a few hundred books, then fifteen minutes a month.
1. Decide what "yours" means, and where books come from
Start with an audit: which of your books can you still open in ten years without permission from a company? That sorts a collection better than genre ever will.
Build the library from books that are unambiguously yours — DRM-free purchases, files converted from copies you legally own where terms and law allow it, public-domain texts, your own documents. Store-locked purchases still count as books you bought; they just live in the retailer's app.
| Source | Typical format | What to do with it |
|---|---|---|
| DRM-free stores | EPUB, sometimes PDF | Import directly; the ideal case |
| Books sold direct by authors | EPUB plus PDF | Read the EPUB, archive the PDF |
| Public domain archives | EPUB, TXT, scanned PDF | Import, then clean the poor metadata |
| Kindle formats you own | KFX, AZW, AZW3, MOBI | Convert to EPUB where permitted |
| Protected store purchases | Vendor container | Read in the vendor app; no portability |
| Work and study documents | PDF, TXT | Import into their own collection |
| Audiobooks you own | Vendor audio container | Handle separately from books |
Everything here assumes personal use of content you legally own. Back up and convert only what you are entitled to, follow the terms of the store that sold it, and respect your local copyright law.
2. Normalize your formats before organizing anything
Format normalization first, cataloguing second. Reverse the order and you do the metadata work twice, because conversion rewrites the file your library points at.
Aim for reflowable EPUB as the house format and PDF where page design carries meaning. EPUB lets each device pick its own line length, font and margins, which is why it survives the jump from a monitor to a phone. Keep the original of every converted book in a separate archive folder; converters improve.
Which guide you need depends on your starting point:
- Mixed Kindle-era files: how to convert Kindle books to EPUB, starting with the container.
- Kindle Format 8 files: AZW3 to EPUB.
- Newer Kindle downloads: KFX to EPUB, which behaves unlike MOBI.
- Going the other way for an e-reader you own: start with EPUB to Kindle if the source is EPUB, or the wider converting to Kindle formats matrix for mixed files.
- Sharing or printing a chapter: EPUB to PDF. If you are still choosing a master format, read EPUB vs PDF first.
- Audible titles you purchased: they are AAX, not EPUB. Convert them locally with How to Convert Audible AAX to MP3, then keep the MP3s beside the ebook archive. Tool shortlist: best Audible converters.
- Choosing a tool: the converter roundup and cross-platform options.
Fere Convert is the paid desktop companion for this stage on Windows and macOS, built on Epubor Ultimate technology. It reads KFX, AZW, AZW3, MOBI, PRC, EPUB and PDF, and turns Audible audiobooks you own into common audio formats: see Fere Ultimate, the Kindle backup tool or the Audible tool.

3. Clean metadata and covers so the shelf is usable
Reader apps sort on embedded metadata, not filenames. That one fact explains almost every ugly library: forty books by "Unknown", a series in random order, three spellings of one author.
Cleaning is dull but fast, and the highest-leverage hour in this guide. Work in batches on the desktop, where multi-select makes it bearable.
-
Import everything first, then judge
Drag your folders in at once. Covers are detected automatically, so gaps in the grid show which files need attention.
-
Fix author names before titles
Authors drive sorting and browsing, so inconsistency hurts most there. Pick one form — "Ursula K. Le Guin", not three — and apply it everywhere.
-
Repair titles and series order
Strip the noise publishers embed: "A Novel", edition banners, store suffixes. Number series entries so book ten does not sit between one and two.
-
Deal with the coverless books
A missing cover means you will never spot the book while scrolling. Fix it while the batch is open.
-
Hunt duplicates
Sort by title and check neighbours. Duplicates come in pairs: the download and its converted version. Keep one, archive the other.
-
Set ratings and status as you go
Book details hold a rating and reading time. Marking the obvious cases now turns a pile into a queue.
A naming convention, deliberately shallow because the reader does the organizing:
- One library root.
D:\Library\Books, plusD:\Library\_Originalsfor pre-conversion masters. - One folder level, by author.
Books\Le Guin, Ursula K\. Deeper trees are maintenance you will abandon. - Predictable filenames.
Author - Title (Year).epub, andAuthor - Series 02 - Title.epubfor series. - Portable characters only. Colons, question marks and trailing dots break elsewhere.
- A quarantine folder.
_Inboxfor uncleaned arrivals, so half-processed files never reach the shelf.
4. Organize the shelf: collections, status and sorting
With clean metadata, organization stops being filing and becomes decision-making. Opening the library should answer a question, not present a wall.
Fere Reader gives you two complementary systems. Fixed groups — All, Want to Read, Finished, Books and PDF — need no upkeep. Your own collections sit alongside them for whatever matches your life: a course, a project, a series, the pile for the next flight. Switch between grid view for browsing and list view for density, and sort by last read, title, author or a manual order.
Three habits keep a large shelf pleasant:
- Cap the active set. Keep "reading now" under five books; the rest waits in Want to Read without guilt.
- Use status, not folders, for lifecycle. Finished books should leave your sight without leaving the library.
- Separate documents from books. Work PDFs get their own collection, so the shelf stays a place for pleasure.
On a PC, the Windows reader comparison covers desktop options, and reading EPUB on Windows is the quick start.
5. Make the reading itself yours
Everything so far was preparation. This part decides whether you use the library at all, so give it ten minutes.
Typography first: pick a font, then adjust size, line spacing, margins, alignment and bold weight until a page feels effortless on the device you hold most. Spacing and margins matter more than font choice, and most people set them too tight. Choose a theme per environment and a page-turn style from slide, scroll, curl or cover.
Then use the annotation tools deliberately, because they are the part no store can hand back if it disappears:
- Highlights and underlines for passages you will want again, kept sparse enough to mean something.
- Notes for the thought you had, not the sentence you read.
- Bookmarks for structural places: the map, the glossary, the chapter you re-read.
- In-book full-text search for a phrase you remember, and the table of contents with its progress percentage.
Fere Reader is free, with no ads, no subscription and no hidden fees, and opens EPUB, PDF, MOBI, AZW3, FB2 and TXT — plain text gets automatic chapter splitting and multiple encodings.
- Normalize formats before cataloguing, or you will do the metadata work twice.
- Clean author names first: they drive sorting, browsing and search.
- Keep folders shallow; let collections, status and sorting organize.
- Annotations and progress are library data, so sync and back them up too.
- Open formats plus a sync target you own means nothing can strand your collection.
6. Sync across devices, and move files without the cloud
A personal library needs two transport mechanisms, and confusing them causes most frustration. Small data changes constantly and must be current; large files change rarely and are expensive to copy.
WebDAV sync handles the small, constant part: progress, notes, highlights and library data. Enter the URL and credentials for Nextcloud, Jianguoyun or any WebDAV-compatible service in Backup and Sync, use test-connection once, then sync on demand or let automatic backup handle it. The endpoint is storage you already control.
LAN sharing handles the large part. The desktop app exposes its library to another device on the same network through a link or QR code: you browse and upload from that device's browser at local network speed.
Two properties matter: Fere Reader is fully offline capable, and sync runs only when triggered, so nothing uploads in the background. You get silence, and the responsibility to sync before switching devices. For the full cross-device picture, read the cross-platform reader comparison, or the Apple Books alternative guide if you are leaving Apple.
7. Back it up properly, on a 3-2-1 pattern
Sync is not backup. Sync faithfully reproduces your mistakes: delete a collection on one device and it disappears everywhere. A backup is a copy frozen in time that no live process can reach.
The 3-2-1 rule adapts neatly: three copies, two kinds of media, one off-site.
| Copy | Where it lives | What it contains | Refresh |
|---|---|---|---|
| Working copy | The device you read on | Library, files, progress and notes | Continuous |
| Local archive | External drive or NAS | Full local backup export plus the originals folder | Monthly |
| Off-site copy | WebDAV storage or a drive kept elsewhere | The same export, one generation behind | Quarterly |
The full local backup export makes this practical: one file holding the library structure and your annotations, not just loose books. Two rules separate a backup from an illusion.
- Keep generations. Three dated copies cost almost nothing and cover corruption nobody noticed for a month.
- Test a restore once. An untested backup is a hypothesis.
8. Keep the habit, not just the collection
The failure mode of a beautiful library is admiring it. The insight tools exist to close that gap.
Reading statistics track days read, books finished and notes taken — enough to see a pattern without turning reading into a performance review. Continue reading puts the book you are in one tap away, because friction kills habits. The want-to-read list holds intentions so they stop cluttering the shelf. Daily and yearly goals suit some readers and irritate others: if a streak gets you reading before bed, use it; if it makes you skim to hit a number, turn it off.
A monthly maintenance checklist, about a quarter of an hour:
- Empty the
_Inboxfolder: convert, clean metadata, file into collections. - Mark what you have abandoned, so the active set stays honest.
- Sync every device before and after the session.
- Export a fresh backup and rotate out the oldest generation.
- Skim Want to Read and delete what you will never open.
- Once a year, run storage cleanup to clear caches and orphaned files.
9. Plan for the long term
A personal library is a thirty-year project. The apps will change; the collection should not have to.
Prefer open formats
EPUB and PDF are documented standards implemented by dozens of independent programs. A proprietary container is a bet on one company's roadmap.
Keep metadata inside the files
Metadata embedded in the EPUB travels with the book to any reader; metadata living only in one app's database is a hostage. Fix titles and authors at file level and the shelf rebuilds correctly in whatever you use next.
Own the sync target
An endpoint you control — your own WebDAV service, your own NAS — means that if a reading app disappears tomorrow, your data is still where you put it. That is the practical meaning of no vendor lock-in.
Assume you will migrate
Design so leaving is cheap: open files, embedded metadata, exported backups, a folder structure a human can read. The converter buying guide and the Kindle to EPUB roundup both weigh portability, and the guides hub collects everything.
Frequently asked questions
How many books do I need before a real library is worth the effort?
Usually between fifty and a hundred titles, or earlier if your books are spread across several devices. Below that a folder works. Above it you start losing books you own and abandoning half-read titles because nothing surfaces them.
Should I keep the original file after converting a book to EPUB?
Yes. Keep it in a separate archive folder your reader never touches. Converters improve, and a future version may produce a better EPUB. The converted file is your reading copy; the original is your master.
What folder and naming convention works best for ebooks?
Keep it shallow: one library root, author folders, and files named Author - Title (Year).epub, with series entries numbered as Author - Series 02 - Title.epub. Two levels are enough, because collections and reading status do the real organizing.
Is a self-hosted library server better than a reader app?
It is better at cataloguing and worse at reading. Calibre with Calibre-Web gives unmatched metadata tooling and a browser-accessible collection, at the cost of running a server. A reader with WebDAV sync gets most of the benefit with none of that.
How often should I back up an ebook library?
After any large import or annotation session, and monthly at minimum. Sync is not a backup because it propagates deletions, so the export protects you from your own mistakes as well as hardware failure.
Which format is safest for long-term storage?
EPUB for reflowable text, PDF where the page layout is the content. Both are open, documented and readable by dozens of independent applications, which is the only meaningful definition of a safe archive format.
