Picture one book in your Seekquel library. It's mid-read, borrowed from a friend, tagged book club, and shelved under Summer Horror. All at once. Those four labels don't touch each other. Change one, and the other three stay exactly where you left them.
That independence is the part people miss. Most reading trackers fake ownership with a shelf named "Own it," or bury tags inside a status field. Seekquel keeps the three apart on purpose. Each one answers a different question:
Where are you in the book? Reading status.
How do you want to group it? Tags and shelves.
What's true about the physical or digital copy? Ownership.
This guide walks through each one, then covers combinations that solve real library problems.
Reading status happens automatically
Reading status is the only one of the four you don't build yourself. Every book you add lands in one of five states: Want to Read, Reading, Paused, Read, or Did Not Finish. It's a single value, so a book can't be "Reading" and "Read" at once. Moving it forward replaces the old status. It doesn't stack.
Status also drives your default shelves. Mark a book "Reading," and it lands on your Currently Reading shelf, no dragging required. Finish it, and it moves to Read. You never touch this list by hand.
There are two kinds of shelves
The word "shelf" covers two different things in Seekquel, and the app keeps them apart on purpose.
Default shelves come from reading status. Want to Read, Reading, Read. These exist the moment you add your first book. You can't rename them, delete them, or add anything to them by hand. They're a live view, not a list you maintain.
Custom shelves are the ones you build yourself. Each one has a name, a color, a position in your shelf list, and an optional description. You can also decide whether it's public, so other readers can browse it on your profile. Unlike a default shelf, one book can sit on several custom shelves at the same time. A book on "Summer Horror" can also live on "Buddy Reads" and "Backlist I'm Finally Reading." No conflict there. No limit on the pairing.
The one real constraint is the free-plan cap on custom shelves. Go over it, and the oldest extra shelves lock read-only until you delete some or upgrade.
The in-app tour puts the split in one line: "Books are automatically organized by status. Create custom shelves to group them your way." Default shelves happen to you. Custom shelves are yours to design.
Tags are your own vocabulary
Every book in Seekquel's catalog already carries genres, moods, and content warnings. That's shared information, the same for every reader who opens the book. Tags are the opposite: private, personal labels you invent for your own library. A tag you create is yours. It never touches the catalog, and it never shows up on someone else's copy of the same book.
You apply tags from a simple picker. A separate screen lets you merge two tags that turned out to mean the same thing. That's handy once you've typed "cozy" into one book and "cosy" into another. Tag names lowercase automatically, so casing never splits one idea into two entries.
Tags cover what the catalog can't know: how you found the book, who recommended it, whether it's a reread, which format you consumed. Genres describe the book. Tags describe your relationship to it.
Ownership tracks the copy in your hands
Ownership is narrower than the other two. It answers one question: what's actually true about this specific copy? Seekquel supports six states: Owned, Borrowed, Lent, Sold, Donated, and Wishlist.
Borrowed and Lent carry extra context you can fill in: who you borrowed it from or lent it to, and the date. That detail gets used. Six months out, "Lent" alone won't tell you who has your copy. "Lent to Priya, June 3" will.
Only four of the six show up as filters and badges in your library view: Owned, Borrowed, Lent, and Wishlist. Sold and Donated are history, not an active shelf state. You can still set them on a book, but Seekquel won't surface them as something to browse. A book you sold months ago isn't part of your current library anymore.
When to reach for a tag instead of a shelf
Both group books. The choice comes down to how long the grouping should last, and how many books belong to it.
Reach for a shelf when the grouping is a real collection you'll come back to. A themed reading list for October. A permanent home for every graphic novel you own. A shared shelf you're building with a friend for a buddy read. Shelves also carry a name, a color, and a description. That makes them something you'd actually show someone else.
Reach for a tag when the label is quick, personal, and likely to apply across shelves. "Reread," "audiobook," or "recommended by Priya" aren't collections you browse on their own. They're notes you want attached to a book no matter which shelf it's on. A single book can carry five tags without the clutter a fifth shelf would create.
A rough rule: if you'd browse that group later, make it a shelf. If you'd mostly use it to filter, make it a tag.
What one book's full picture looks like
Status, tags, shelves, and ownership are all separate. One book can carry all four without any of them overwriting another. Take a copy of "The Fifth Season." You own it outright. You're currently reading it. You've tagged it as a reread and a book-club pick. It sits on both your "Summer Horror" and "Buddy Reads" shelves. All five facts live side by side. Marking it finished later won't touch the tags, the shelves, or the fact that you own it.
Combinations that solve real problems
The separation pays off when you go looking for something specific. Seekquel's library filters treat tags, ownership, and shelves as independent choices. You can stack them to ask compound questions a single-field system can't answer.
What do I still need to return? Filter ownership to Borrowed. Status and shelf don't matter here, since a borrowed book can be unread or half finished and you'd still want it on the list.
What owned books haven't I started? Owned plus Want to Read, at the same time. This is the filter for "what should I actually pick up next," since it skips anything you don't have in hand yet.
Which books on my Buddy Reads shelf am I actually mid-book on? Shelf plus status, combined. Useful before a call with the friend you're reading alongside, so you know who's ahead.
Everything tagged "audiobook" that I still own. Tag plus ownership, no shelf required. Good for a commute, when format matters more than which shelf a book happens to live on.
What's sitting on my Wishlist that I could actually pick up used? Wishlist ownership on its own, with no status or shelf involved, since a wishlist book hasn't been added as reading material yet.
Everything tagged "recommended by book club" that I haven't marked Read. Tag plus status, which surfaces recommendations you've collected but never followed through on.
Which books I own are tagged for a specific season or mood, and haven't been started? Ownership plus tag plus status, three filters at once, for planning something like a themed October reading month from books already on your shelf.
None of these need a workaround. Each is just a combination of independent filters, stacked on information that was never crammed into one field.
The short version
Deciding where a new distinction belongs comes down to one question. Which of the three is it actually answering? "Where am I in this book" is status, and Seekquel moves it for you. "How do I want to group this" is a shelf if it's a durable named collection. It's a tag if it's a quick personal label. "What's true about my copy" is ownership, full stop. It has nothing to do with whether you've read the thing yet.
Keep those three questions separate. The library organizes itself around how you actually think about your books, not around one status field.
