The complete NUR classification as used in Shelvd — every code across ten categories, with context for collectors in the Netherlands and Flanders.
What NUR Is
NUR stands for Nederlandstalige Uniforme Rubrieksindeling — the Dutch-language Uniform Subject Classification. It is the standard system used by the book trade in the Netherlands and Flanders (Belgium) to categorize published works. Every book published in Dutch, and every book sold through Dutch and Flemish trade channels, receives a NUR code.
If you've ever wondered why the back cover of a Dutch paperback says "NUR 301" next to the barcode, this is the system. It tells the bookseller where to shelve the book. It tells the distributor which catalog to list it in. And it tells Shelvd what your book is about — in a way that's specific to the Dutch-language market.
How It Works
A NUR code is a three-digit number between 000 and 999. The first digit indicates the broad category (the hoofdrubriek), and the remaining digits narrow it down:
301
│││
│└┘── Subrubriek: Literaire roman
└──── Hoofdrubriek: 3xx = Literaire fictie
The system is simple, flat, and deliberately non-hierarchical beyond the first digit. There are no decimals, no auxiliary signs, no colons or brackets. A NUR code is a three-digit number, full stop. This makes it the most approachable classification system in Shelvd — and the most geographically specific.
The Ten Main Categories

| 100–199 | Educatief | Educational | Schoolbooks, study guides, teaching materials |
| 200–299 | Kinderboeken | Children's books | Picture books, children's fiction, young adult, educational children's |
| 300–399 | Literaire fictie | Literary fiction | Novels, short stories, poetry, drama, essays, humor, thrillers, SF |
| 400–499 | Vrije tijd | Leisure | Cooking, gardening, travel guides, sports, hobbies, pets |
| 500–599 | Reizen en expedities | Travel | Travel narratives, country guides, regional guides, atlases |

Why Collectors Should Care
If you collect Dutch-language books — or buy from dealers in the Netherlands and Belgium — NUR codes are everywhere. They appear:
- On the back cover, near the barcode
- In distributor databases (CB, Centraal Boekhuis)
- In library catalog records from Dutch and Flemish libraries
- In ISBN registration data from the Stichting ISBN Nederland and ISBN Vlaanderen
For a collector, NUR is useful because:
-
Trade classification — NUR tells you how the trade categorizes your book, which can differ from how a library classifies it. A literary thriller is NUR 305 (Literaire thriller), not DDC 823 or LCC PR. The trade cares about where it sells; the library cares about what it's about.
-
Market context — If you're a dealer selling to the Dutch or Flemish market, NUR codes help buyers find your books. Online platforms like bol.com use NUR codes for categorization.
-
Completeness — If you're cataloging a Dutch book and Library Lookup returns a NUR code, Shelvd resolves it to its full description. "NUR 301" becomes "Literaire roman, novelle" — which is more useful than a three-digit number.
NUR vs. DDC, LCC, UDC
NUR is not an academic classification system. It doesn't attempt to map all human knowledge — it maps the book trade. The differences are instructive:
| NUR | DDC / LCC / UDC | |
|---|---|---|
| Purpose | Bookselling and distribution | Library classification |
| Scope | Dutch-language book trade | Universal |
| Depth | 682 codes, flat structure | Thousands to millions of entries, hierarchical |
| Who assigns it | Publisher, at registration | Librarian, during cataloging |
| Where it appears | Back cover, trade databases | Copyright page, library catalogs |
A book typically has both a NUR code and a DDC/LCC/UDC number. They classify the same book from different perspectives — the trade's and the library's. Neither replaces the other.
A Note on Language
NUR descriptions in Shelvd are in Dutch, because that's the language of the system. A few examples:
| NUR | Description | English equivalent |
|---|---|---|
| 280 | Literaire fictie kinderen t/m 12 jaar | Literary fiction, children up to 12 |
| 301 | Literaire roman, novelle | Literary novel, novella |
| 305 | Literaire thriller | Literary thriller |
| 320 | Literaire poëzie | Literary poetry |
| 440 | Kookboeken, eten en drinken | Cookbooks, food and drink |
| 680 | Geschiedenis | History |
| 730 | Beeldende kunst | Visual arts |
| 910 | Wiskunde | Mathematics |
If you catalog in English and encounter a NUR code, Shelvd's resolution will show you the Dutch description. This is by design — translating NUR descriptions would lose the specificity that makes them useful in the Dutch-language market.
In Shelvd
The NUR field lives in the Subject Classification section of the edit form. Shelvd contains the complete NUR list: 682 codes across ten main categories. Type a code and Shelvd resolves it to its Dutch description and category. Type a description — "thriller" or "wiskunde" — and see matching codes.
The data was compiled from the official NUR list as published by Stichting ISBN Nederland (version 2011, the current edition).
Shelvd's NUR reference table contains 682 entries across 10 categories. During editing, the NUR field provides bidirectional search — type a code or a Dutch description, and Shelvd resolves the other.
