You started a blog because you had something to say, and you kept going long enough for the saying to become a body of work. Somewhere in that archive sit thirty or forty pieces quietly doing the same job in different ways. That is not a folder of posts. It is the rough shape of a book.

What follows is the process an editor would walk you through: choosing the essays worth keeping, editing writing built for a screen so it survives on paper, and arranging the whole thing so a reader keeps going.

Find the spine before you sort anything

Before you open the archive, write one sentence describing what the book is about. Not "a collection of my essays about city life" — that describes a folder. Try: "What it costs to belong to a place that keeps changing." Or: "Ten years of running a small shop without turning into someone I don't recognise."

The sentence will be wrong. It is still worth writing, because it gives every essay a test to pass. Anything that cannot answer to it becomes a footnote, however well it did online.

Read your own work like a stranger

Set aside two or three evenings and read the archive in chronological order. Print it if you can; on screen you will slide into editing and stop reading. Beside you, keep a notebook with three headings: Keep, Maybe, Cut.

You are listening for repeats. Most people who blog for years circle the same four or five subjects — money, family, work, a particular stretch of coastline. That repetition is not a flaw. It is the shape of your material, and it is what makes a book rather than a sampler. It also means you cannot put two essays about your father's shed next to each other and expect a reader to stay patient.

As you sort, ask of each piece:

• Does it stand without the news? A post that only works because of a specific week in 2021 needs a new opening, or a date on the page.
• Does the first paragraph earn the second? If it takes four paragraphs to get going, it may be a keeper with a new start.
• Is it doing a job no other essay does? Two funny pieces about train delays is one funny piece about train delays.
• Is the argument still true? Opinions move. You are allowed to write a new essay that answers an old one, but not to pretend you always thought this.
• Would you be content for it to be the first thing a reader meets? Anything that fails this can still be chapter nine.

Edit for the page, not the feed

Print changes the contract. Online, a reader arrives mid-scroll, already knows who you are, and forgives a great deal. In a book they arrive cold, with no context and no back button.

Cut the scaffolding

Blog essays begin with throat-clearing: apologies for the silence, explanations of why this topic, notes on what else you have been reading. Remove the first paragraph and see whether the essay improves. It usually does.

Turn links and pictures into sentences

If a post said "this piece explains it better", the book needs the explanation, in your words, in a clause or two. If a photograph carried the point, describe it. Nothing should depend on something the reader cannot see.

Tame your tics

Read together, your habits become loud: the same three adjectives, the mid-sentence "of course", the essay that ends on a rhetorical question. Keep the ones that sound like you, cut the ones you did not choose. One essay ending in a question is a device; four is a twitch.

Give each essay one ending

Posts often end twice because the writer cannot bear to stop. Choose the strongest final line and delete everything after it.

Order it as a sequence, not a pile

Think of the collection as rooms in a house. A reader walks through them in the order you set, and each one colours the next. Open with something short and confident rather than your longest, most ambitious piece — save that for the middle, where trust is highest. Vary length and temperature: an argument, then a story, then something quieter. Group loosely into three or four clusters, and accept that a few decent essays will have to go because they break the rhythm rather than because they are weak.

Read the whole sequence aloud over a couple of days before you commit. Awkward transitions are easier to hear than to see.

The new writing that holds it together

A collection needs a little material that was never on the blog: a real introduction of a few pages, short openers for each section, and one or two new essays that bridge clusters which would otherwise sit apart. This is where you get to say what you were doing all that time.

It is also where you handle the practical side. If some posts were commissioned or written for another publication, check what rights you hold before they appear in print. If a piece was co-written, or built on interviews with named people, ask them first. For anything contractual, take proper advice rather than guessing.

An order of work that holds up

Give the project eight to twelve weeks and work in this sequence:

1. Write the spine sentence. Revisit it once at the end.
2. Read everything and sort into keep, maybe and cut.
3. Choose twenty to thirty essays, aiming at a book of roughly 25,000 to 40,000 words; much shorter than that reads as a pamphlet.
4. Edit each essay on its own, on paper, with a pen.
5. Lay the edited essays along a table and rearrange until the sequence feels inevitable.
6. Write the introduction and section openers last, once the shape is settled.
7. Give it to three readers who do not follow the blog, and ask them where they got bored.
8. Then decide how it will be published, which is a separate question with its own answers.

The archive is the hard part, and it is already done. What remains is selecting, cutting and arranging — the work an editor does, and work you are unusually well placed to do well.
