Most people who abandon a commonplace book do it in the first fortnight, and almost always for the same reason: they treated it like a streak.

It isn’t one. A commonplace book has no opinion about you. Skip a month and it waits.

1. One book, not a system

Any notebook will do. The temptation is to spend a week choosing paper and colour-coding a method you have not used yet. Resist it. The method matters more than the paper, and the method is simple enough to explain in a paragraph.

2. Copy it out. Don’t summarise

The exact words, or it isn’t the thing you loved. A summary is your sentence about their sentence, and in six months it will be the summary you remember and the original you lost.

This is also why handwriting matters. Copying out is slow enough that you only do it for passages that earned it. The friction is the filter.

3. Always record the source

Book, author, page. It takes four seconds. Future you will want to quote it to someone and will not remember where it came from — and an unattributed quote is a quote you cannot use.

4. Add one line of your own

Why you kept it. What it made you think. This single habit is what turns a scrapbook into a mind. Without it you have a collection of other people’s sentences; with it you have a record of your own thinking, dated.

5. Index as you go

Two pages at the front. Theme on the left, page numbers on the right. Add to it the moment you write an entry, not later — later never arrives.

Locke published an entire indexing method for commonplace books in 1685 and it stayed in print for a century, which tells you how much people struggled with exactly this. You do not need his system. You need two pages and the discipline to use them.

6. Skip days without guilt

There is no streak to break. Some weeks you read nothing worth keeping. That is information too.

What to put in it

• Quotes worth keeping, with the source and a line on why
• Books read — not what you finished, what it did to you
• Words and language, with one sentence of your own
• Places, sketches, tickets, half-remembered streets
• Things people said that beat anything you read that week
• Letters to your future self, both dates recorded

If you’d rather not build the sections yourself

Our Botanical Series comes with all of it laid out and the index already at the front — Rose for readers, Lemon for Crete, Forest for Slovakia. Print at home, or keep it on your iPad. From €2.99.

Paws to reflect. Pens to express.

Prefer Etsy? The whole Botanical Series is there too — same files, a slightly smaller share of it reaching the dog.
