Declaration on Accessibility

This declaration on accessibility applies to the website of the Staatsbibliothek zu Berlin – Preußischer Kulturbesitz published at

As a public body within the meaning of Directive (EU) 2016/2102, we strive to make our websites and mobile applications accessible in accordance with the provisions of the Act on Equal Opportunities for People with Disabilities (BGG) and the Accessible Information Technology Ordinance (BITV 2.0) for the implementation of Directive (EU) 2016/2102.

State of Compatibility with the Requirements

The accessibility requirements are pursuant to Sections 3 (1–4) and 4 of the BITV 2.0, which was issued on the basis of Section 12d of the BGG.

The verification of compliance with the requirements is based on a self-assessment on the basis of a BITV-WCAG test report carried out between March 15, 2024 and April 3, 2024.

According to the review, the website is only partially compatible with the aforementioned requirements, owing to the following incompatibilities.

The items listed below are classified as not accessible for the reasons given:

  • Explanations in German Sign Language and Easy-to-Read Language are not yet available. Therefore, the website does not currently meet the requirements of §4 of BITV 2.0.
  • Individual graphics do not have alternative text and therefore do not meet requirement 1.1.1 under WCAG 2.1.
  • Some lists are not labeled as lists. Therefore, they do not comply with requirement 1.3.1 of WCAG 2.1.
  • No semantically clear, language-independent determination of the purpose is possible in the contact form. It therefore does not comply with requirement 1.3.5 of WCAG 2.1.
  • No error messages are generated in the contact form if the form is filled out incorrectly, only the corresponding area is outlined in red. This does not comply with 3.3.1 of WCAG 2.1.
  • Links are only identified by color and do not meet the requirement 1.4.1 of WCAG 2.1
  • The contrasts of the foreground and background colors are partially insufficient and therefore do not comply with requirement 1.4.3 of WCAG 2.1.
  • The navigation overlays the content area (in individual cases in the Firefox browser) when enlarged to 200% and therefore does not comply with requirement 1.4.4 of WCAG 2.1.
  • When displaying code, you have to scroll horizontally with a browser window width of 320 pixels. This does not comply with requirement 1.4.10 of WCAG 2.1.
  • Individual slideshows cannot be paused and flashing elements may occur in rare cases, therefore this does not comply with requirement 2.2.2 of WCAG 2.1.
  • Content is not clearly highlighted by the keyboard focus and therefore does not comply with requirement 2.4.7 of WCAG 2.1.
  • Linked PDF files are partially not fully usable in an accessible manner in the sense of the requirements of WCAG 2.1.
