About

Store norske leksikon (SNL) is a free Norwegian reference work covering all topics and fields, with articles in Bokmål and Nynorsk. Subject editors are selected experts who maintain their areas, write content and provide academic quality control. Registered readers can propose new articles or changes; an editor reviews submissions before publication. Articles are intended to use clear language, structured headings, definitions, fact boxes and links to related material. SNL says its content is useful to pupils, students and teachers, and many articles are linguistically adapted for school pupils. Reading requires no account, though accounts are needed to submit proposals or comments and send internal messages. The works have an open API and metadata marked for free reuse, and content is updated daily. SNL says AI-generated text may not be published in the encyclopedia. It is available on the web, iOS and through an API. The publisher reports that some explanatory image captions are not adapted for screen readers, while related information is also provided as article text. The nonprofit association operating SNL was established in 2014.

Inferse review

Store norske leksikon: the full review

SNL combines expert editorial review with broad Norwegian-language coverage and open API access. It is a practical reference source for readers and builders, with a noted limitation in some image-caption accessibility.

Store norske leksikon is a free Norwegian reference work, written and maintained by subject experts. It best suits Norwegian-speaking readers, especially pupils, students, and teachers. Its editorial oversight and open API make it useful both as a reference and as a source for builders, though its image-caption accessibility has a known limitation.

Overview

SNL covers all topics and fields in Bokmål and Nynorsk, with articles based on research. Subject editors maintain assigned areas, write content, and provide academic quality control. That model gives readers expert stewardship; it also means reader suggestions are proposals, not instant edits.

Anyone can read without an account. Registered users can submit article or change proposals, which an editor reviews before publication. The publisher does not permit AI-generated text in the encyclopedia. Founded in 1978, SNL is operated by the nonprofit, non-commercial association Store norske leksikon, established in 2014.

Key features

Editorial guidance calls for clear language, structured headings, definitions, fact boxes, and links to related material. Many articles are linguistically adapted for school pupils, making the resource particularly practical for learning and classroom use. Text and images, citation tools, and daily updates support both quick reference and more considered reading.

For developers, the publisher provides an open API and metadata marked for free reuse. This makes SNL a plausible source for projects that need Norwegian reference content, though the API and reuse statement do not establish specific integration features or service guarantees.

SNL aims to meet most WCAG 2.0 AAA requirements and all AA requirements, and says it fixes errors as they are found. Some explanatory image captions are not adapted for screen readers; the relevant articles also provide the information in text. The publisher collects de-identified, aggregated visitor statistics and uses Google Analytics on its website.

Pricing

Free access: 0.00 USD per free. The plan provides a freely accessible reference work, with no free trial because access is already free. There are no paid tiers or stated account requirement for reading. Registration is needed only for comments, proposals, or internal messages. The free model is a strong fit for individual readers, schools, and teams evaluating Norwegian reference content without a subscription commitment.

Platforms

SNL is available on web, iOS, and through an API. The combination gives readers browser and mobile access while offering builders a route to use its content and metadata in software. No Android platform is offered.

Who it's for

SNL is the right choice for Norwegian-speaking readers who value expert-maintained material in Bokmål or Nynorsk, particularly pupils, students, and teachers. Builders needing reusable Norwegian reference data should also consider it because the publisher says its API is open and its metadata is marked for free reuse. It is less suitable when a project depends on another language or when screen-reader-adapted explanatory image captions are essential.

Pros and cons

  • Pros: Expert editors provide academic quality control across assigned subject areas, a useful distinction for readers who want accountable editorial stewardship.
  • Pros: Bokmål and Nynorsk coverage, including material adapted linguistically for pupils, supports a broad range of Norwegian readers.
  • Pros: Free access, daily updates, citation tools, and an open API with metadata marked for free reuse suit both readers and builders.
  • Cons: Some explanatory image captions are not adapted for screen readers, which can make that content less accessible despite accompanying text.
  • Cons: The encyclopedia is centered on Norwegian-language coverage, so readers or products requiring other languages need another source.
  • Cons: User contributions pass through editorial review before publication, favoring quality control over immediate community edits.

Alternatives

For a broad comparison of reference sources, see Online Encyclopedias. Choose Wikipedia instead when a free encyclopedia with Android, iOS, web, and API access is a better platform fit. Encyclopedia of Arkansas is another free web encyclopedia. Consider Encyclopedia.com for its more than 300,000 reference entries and over 50,000 topic summaries, or The Canadian Encyclopedia for a free bilingual English-and-French resource.

Infoplease and Te Ara – The Encyclopedia of New Zealand are also free web alternatives. Treccani may suit readers seeking ad-free browsing across devices, with duration selectable in the app and up to six months free. World Book Online is a paid option at 250.00 USD per year for individual access, with discounted multi-user institutional pricing available; it may fit organizations seeking a subscription with institutional pricing.

Verdict

Choose Store norske leksikon for free, research-based reference content in Bokmål or Nynorsk, especially if expert editorial review or an open API matters to your work. Its strongest case is the pairing of subject-editor oversight and broad Norwegian coverage without a reading fee. Look elsewhere if you need content in other languages, Android access, or explanatory image captions fully adapted for screen readers.
