Two authors sit down with the same manuscript. One spends a year and a half writing query letters, refining a proposal and waiting for an answer. The other books an editor, commissions a cover, uploads three files and has a paperback on sale within a fortnight. Both are publishing. Neither route is the "proper" one, and the choice has far less to do with prestige than with what you want the book to do for you.

What each route actually involves

Traditional publishing means a publisher buys the right to produce and sell your book. For most trade non-fiction, that starts with a literary agent, because the larger houses rarely read unsolicited submissions. Non-fiction is usually sold on a proposal rather than a finished manuscript: an overview, a chapter outline, a sample chapter, a note on who will read it and why you are the person to write it. Smaller presses and academic publishers often accept direct submissions, so read their guidelines before assuming you need an agent.

Self-publishing means you are the publisher. You commission the editing, the cover and the interior layout, buy your own ISBNs from Nielsen in the UK, and upload the finished files to retailers such as Amazon, Kobo, Apple Books and IngramSpark. You set the price, you keep the rights, and you carry the risk.

Costs: where the money goes

With a traditional deal, money flows towards you. The publisher pays an advance against royalties, covers editing, design, printing and distribution, and pays you a percentage of sales once the advance has earned out. Agents take a commission on what you earn, commonly fifteen per cent for UK and Commonwealth rights and twenty per cent for translation and screen deals. You will still be expected to help with marketing, and advances are often paid in instalments rather than in one go.

Self-publishing flips the flow. Nothing is deducted from future sales, but you pay now, and the list is longer than most first-timers expect:

• Developmental or structural editing: the big-picture work on argument, order and audience
• Copy-editing and proofreading, which are two separate jobs
• Cover design, including spine and back for print
• Interior formatting for print and e-book
• ISBNs, one per format, bought from Nielsen
• An index, if your book needs one
• Audiobook production, if you want it
• Launch costs: review copies, advertising, or a publicist

Two things are worth knowing early. Copyright is automatic in the UK as soon as your work is written down, so you do not register it, and nobody can sell you protection you already have. And the money you save on editing or cover design is usually visible to readers on page one.

Timelines

Traditional publishing is slow, and part of that slowness is deliberate. Finding an agent can take months or years. Submission to publishers takes more months. Then comes a contract, an editorial cycle, a production schedule and a slot in a catalogue that may be a year away. Twelve to twenty-four months from signed contract to bookshop is ordinary. If your subject is topical, that gap matters a great deal.

Self-publishing runs on your own calendar. Book the editor before you finish the draft, keep the cover brief tight, and a realistic schedule from finished manuscript to saleable book is a matter of months rather than years. The bottleneck is not technology. It is your own quality control, and your willingness to wait when something is not ready.

Rights, royalties and control

A traditional contract usually asks for volume rights, and often audio, translation and film as well. What matters is the detail: how long the publisher holds those rights, when they revert to you, what happens if the book goes out of print, and whether a non-compete clause stops you writing something similar elsewhere. Read those clauses before you sign, and get a second opinion. The Society of Authors offers contract advice to members, and a solicitor who works in publishing is worth the fee on anything substantial.

Self-publishing leaves every right with you. You can sell a translation, license an audiobook, or fold the book into a course. Retail platforms typically pay a percentage of the list price on e-books and the list price minus printing costs on paperbacks, which often works out higher per copy than a traditional royalty. The trade-off is volume: without a publisher's sales team behind you, you are unlikely to shift as many copies. Register with Public Lending Right and with the Authors' Licensing and Collecting Society so that library loans and secondary uses pay you something.

Distribution and getting into shops

Online retail is straightforward on both routes. Physical bookshops are the hard part. A traditional publisher has a sales team, a trade catalogue and accounts with wholesalers, so shops can order your book the way they order everything else.

Self-published authors have to build that path themselves. A bookshop needs a standard trade discount, a returns arrangement it can live with, and a reason to give shelf space to an unknown title. Print-on-demand makes returns awkward, which is why many self-publishers focus on local shops, events and direct sales, treating national chains as a bonus rather than a plan. Walk in with a finished copy, a one-page summary and a clear offer. It works more often than you would think.

How to choose: a practical checklist

Answer these honestly before you commit either way.

1. Do you want an advance and someone else's sales team, or full control and a bigger share of each sale?
2. Is there a clear, identifiable readership for this subject, and can you name the organisations, publications or events that reach them?
3. Can you fund professional editing and design without borrowing money?
4. Do you have a platform already, such as a newsletter, a speaking schedule, a professional body or a course, or are you starting from nothing?
5. How quickly does the book need to exist? Some subjects will not wait two years.

Many authors stop treating this as a binary choice. A traditional deal for the book that suits it, a self-published companion volume, a self-published backlist once rights revert: all of that is normal now. Pick the route that matches your subject, your budget and your temperament, and give the book the editing it deserves whichever door you walk through. If you are signing a contract or handling royalty income, take proper legal and tax advice before you commit.
