Licensing and attribution

Provenance of the material presented by the Service, and the terms applicable to it.

Article text

The articles presented by the Service reproduce the text of the corresponding articles of the English-language Wikipedia, authored by its contributors and published under the Creative Commons Attribution-ShareAlike 4.0 International licence (“CC BY-SA 4.0”).

Attribution

Attribution is effected in the manner provided by Wikipedia's guidance on the reuse of its content. Each article page of the Service links to the source article, the revision history of which contains the complete list of contributing authors. That link appears beneath the article title and is marked “On Wikipedia”, and is repeated at the foot of each article together with a link to the revision history.

Modifications

Article text is not reproduced verbatim. CC BY-SA 4.0 requires that modifications be indicated. The modifications made are as follows:

  1. Navigational and editorial apparatus is removed, comprising navigation boxes, sister-project boxes, authority control data, section edit links, maintenance banners and the round-tripping metadata emitted by Wikipedia's parser.
  2. Sections constituting apparatus rather than article prose, namely References, See also, External links, Further reading, Bibliography and equivalent headings, are removed from the body. Footnotes are retained and presented in a collapsed panel following the article.
  3. The infobox, where present, is presented in a collapsed panel headed “Quick facts” rather than adjacent to the opening paragraphs.
  4. Links to other Wikipedia articles are rewritten to address the corresponding page of the Service where one exists, and are otherwise left addressing Wikipedia.
  5. Images and tables are constrained to the width of the reading column, and a table of contents is derived from the article headings.
  6. Typography, colour, text size, justification and the display of an opening initial are determined by the Service and form no part of the source article.

No sentence of article prose is rewritten, reordered or supplemented. The modifications set out above are structural. The unmodified article is available by means of the link referred to in the preceding clause.

Licence of the adapted material

The articles presented by the Service being adaptations of material licensed under CC BY-SA 4.0, the ShareAlike condition applies, and the adapted text is made available under CC BY-SA 4.0. It may be reproduced, adapted and used commercially, subject to attribution of the original authors, indication of modifications made, and licensing of any resulting work under the same terms.

Assessment questions

Assessment questions are generated by a language model from the article text and are reviewed manually before publication. Being derived from material licensed under CC BY-SA 4.0, they are likewise made available under CC BY-SA 4.0. They are not the work of Wikipedia or its contributors, who bear no responsibility for them. Defects should be reported by means of the facility provided beneath each question and not to Wikipedia.

Software

The source code, templates and stylesheet of the Service are distinct from the material described above and are made available under the MIT licence, which permits any person to operate an independent instance of the software.

Images

Images are not covered by the licence applicable to article text. Each image is subject to its own terms, which may comprise a public domain dedication, a Creative Commons licence or a more restricted permission, and which are recorded on the corresponding file page at Wikimedia Commons or at Wikipedia. Any reuse of an image must be assessed against that file page, and the licence applicable to the surrounding text may not be relied upon.

Reading list

The selection of articles and their assignment to levels and categories is derived from Wikipedia:Vital articles, a list maintained by Wikipedia editors and likewise licensed under CC BY-SA 4.0. The levels, categories and membership of that list are the work of its editors. The reading order, the proposal of what to read next and the assessments are not.

Typefaces

The opening initial of each article is set in Missaali, by Tommi Syrjänen, reconstructed from the Missale Aboense printed by Bartholomeus Ghotan in 1488. The reading typefaces are Literata, Source Serif 4, EB Garamond, Inter, Atkinson Hyperlegible Next and JetBrains Mono. Each is licensed under the SIL Open Font Licence, which requires that the licence accompany the font. A copy is accordingly served with the files to which it relates:

All typefaces are served from the Operator's own server. No font is retrieved from a content delivery network or other third party.

Icons and scripts

Interface icons are taken from Phosphor and are licensed under the MIT licence.

The sole third-party script is htmx, version 2.0.4, by Big Sky Software, licensed under the Zero-Clause BSD licence. It is served from the Operator's own server.

Corrections

Any claim that material is incorrectly attributed, or that an image is used without adequate permission, may be addressed to ant.karvelas@pm.me, and the material will be corrected or withdrawn.
