1. The Story Behind the Day
From access-to-information advocacy to an international observance
UNESCO's General Conference proclaimed 28 September as International Day for Universal Access to Information in 2015 through 38 C/Resolution 57. UNESCO states that the observance has been marked since 2016 and that the 74th UN General Assembly subsequently proclaimed 28 September at UN level in October 2019.
The UN observance page places the day in a freedom-of-information context: people need access to information in order to participate in public life, hold institutions accountable and exercise freedom of expression.
This origin should remain central. The day is not primarily a digital-accessibility campaign, although digital accessibility is increasingly relevant to whether information is universal in practice.
What “universal access” demands
A document can be public and still be inaccessible. It may be behind a paywall, written only in specialist language, published as an image that assistive technology cannot read, available only in one language, difficult to navigate on a phone or understandable only to people who already know the system.
Universal access therefore involves several layers: legal permission, technical availability, accessibility, comprehensibility, affordability and trust.
No single format can satisfy everyone. A long policy report may need a plain-language summary. A video may need captions and a transcript. A public service may need information in multiple languages and alternative communication formats.
Disability rights add a crucial access dimension
The Convention on the Rights of Persons with Disabilities reinforces this broader meaning. CRPD Article 21 calls for public information in accessible formats and recognises sign languages, Braille, augmentative and alternative communication and other accessible means.
That does not redefine the UNESCO day as a disability observance. It shows that universal information access cannot be achieved if disabled people are expected to rely on someone else to interpret inaccessible systems.
2. What Can We Learn?
Availability is not the same as usability
Organisations often assume transparency once a PDF has been uploaded. But access depends on whether a person can find the right document, understand its purpose and use it with the technology or communication method they rely on.
This distinction matters especially for public services, healthcare, education and rights information. Information that is technically open but practically unusable can still exclude.
Cognitive accessibility is part of information access
Dense text, unexplained acronyms, unpredictable navigation and long chains of instructions can create barriers for many people, including people with learning disabilities, ADHD, dyslexia, intellectual disabilities, language differences or cognitive fatigue.
Clear structure is not “dumbing down.” Good headings, short explanations, examples, summaries and visible next steps make complex information easier to navigate while preserving detail for readers who need it.
Too much information can also be a barrier
Digital systems make it easy to publish everything. They do not automatically help people identify what matters.
A user facing fifty nearly identical documents may technically have access but little practical orientation. Version dates, concise summaries, clear labels and archiving outdated material are information-access tools too.
Trust affects whether information is usable
People need to know where information comes from, when it was updated and whether an organisation is distinguishing fact from opinion. This is especially important in health, rights and public-policy contexts where misinformation can cause harm.
Transparent sourcing therefore belongs inside accessibility. A readable claim without provenance can still fail the reader.
3. What Needs to Change?
Publish accessible source formats by default
Scanned PDFs, images of text and unstructured documents continue to exclude users of screen readers and other tools. Organisations should create semantic headings, selectable text, meaningful link labels, alt text where needed and keyboard-accessible interfaces.
Accessible HTML is often a strong default for public information because it adapts across devices and assistive technologies.
Write for people who did not design the system
Institutional information is frequently written from the organisation's perspective: department names, policy numbers and internal processes come first. Users need task-based information: what this is, who it is for, what to do next, what it costs, what the deadline is and where to get help.
Changing the information architecture can be more important than simplifying individual sentences.
Offer alternatives without forcing people to ask repeatedly
If every accessible version must be requested individually, access is delayed and disclosure becomes part of the price of participation.
Common alternatives should be available proactively where feasible: HTML, tagged documents, captions, transcripts, easy-read/plain-language material, sign-language information and contact routes that do not depend only on phone calls.
Preserve rights and nuance when simplifying
Plain language should clarify, not erase. A benefits explanation that omits an eligibility exception may be easier to read but less accurate. A consent form that hides risk in simplified wording is not genuinely accessible.
Good information design layers complexity: a concise explanation with routes to full detail, rather than a choice between legal jargon and incomplete summaries.
Accessibility should survive updates
A one-time remediation project can fail as soon as new content is published. Templates, editorial workflows, procurement standards and staff training need to make accessibility repeatable.
Quality assurance should include assistive-technology and cognitive-access checks, not only visual design approval.
Searchability is part of access
People cannot use information they cannot find. A website may contain a correct policy while search labels, navigation and filenames hide it from the person who needs it. Search terms should reflect the words users are likely to use, not only internal department language.
Archiving matters too. Old guidance that ranks above current guidance can create a new form of misinformation. Visible update dates and clear superseded notices help readers judge what is current.
Language access and cognitive access overlap but are not identical
Translation can make information available in someone's strongest language, while plain language can make a complex process easier to understand. Neither automatically replaces the other. A translated legal document may still be difficult; a simplified English summary may still exclude a non-English reader.
Universal access therefore benefits from layered formats: accurate originals, translations where needed, concise summaries and routes to ask questions.
Artificial intelligence raises new information-access questions
AI tools can help people summarise or navigate information, but they can also produce confident errors or obscure where a claim came from. Organisations should not assume that an AI interface solves accessibility by itself.
High-stakes information should remain available in authoritative, accessible source pages. Where AI assistance is offered, users should be able to see provenance, reach the underlying source and know when a system may be uncertain. Access without reliability is not meaningful access.
Privacy can be an access issue
Some services make users disclose disability, diagnosis or personal circumstances before providing an accessible format. That can discourage use, especially when the information is unrelated to eligibility.
A better design makes common accessibility options available to everyone and collects sensitive information only when genuinely necessary. Universal design can reduce both administrative burden and privacy cost.
Access also depends on timing
Information can arrive too late to be useful. An accessible voting guide published after registration closes, a translated school notice sent after the meeting, or an accommodation policy revealed only after an application deadline does not create equal access.
Organisations should include timing in information governance: identify when people need to know something, publish early enough for questions and updates, and make changes visible rather than silently replacing files. Timeliness is part of usability.
People need routes to challenge and correct information
Universal access is not only one-way publication. People may discover an error, an inaccessible document or an instruction that does not match reality. Clear contact routes and correction processes help information systems learn.
Feedback channels themselves need to be accessible. A phone-only complaint line or a web form that times out quickly can block the people most affected by poor information design.
4. What Can You Do?
Take Part — Use your right to information
Choose one public decision, service, policy or issue that affects you and find its original source. Compare summaries with the underlying document, ask for clarification where needed, and note which formats make the information genuinely usable for you.
Show Your Support — Help useful information travel without stripping away context
When sharing a complex document, add a short plain-language explanation of what it is, who it affects, when it was updated and where the original sits. If someone encounters an access barrier, help them reach an alternative format without speaking over their needs.
For Organisations — Test an information journey from start to finish
Pick a real task such as checking eligibility, booking support or understanding a policy. Follow it on a phone and with keyboard-only navigation, add human-readable summaries with provenance, and remove format monopolies by providing structured HTML, transcripts, text contact or properly tagged documents where needed.
5. Explore the Movement
The UNESCO International Day for Universal Access to Information page documents the 2015 proclamation and the later UN recognition. The United Nations observance page connects the day to freedom of expression, public accountability and inclusive knowledge societies.
For disability-related information rights, CRPD Article 21 provides a clear international framework for accessible formats and communication choices.
Related Calendar 5.0 observances include Global Accessibility Awareness Day, International Day of Sign Languages, World Braille Day, International AAC Awareness Month, International Day of Persons with Disabilities and World Press Freedom Day. Their purposes overlap in access but arise from different histories.

6. Why This Day Matters to the Neurodiversity Foundation
Information access is central to NDF because many barriers described as individual difficulties are made worse by the way information is structured.
A person may be able to understand a complex decision but struggle with a page that hides the next step. Someone may read well but lose track in an unstructured wall of text. Another may need extra processing time, text rather than speech, or a predictable sequence before they can respond.
Neuroinclusive information therefore means more than using simple words. It means designing for orientation, choice, multiple formats and reduced unnecessary cognitive load.
NDF also needs to model source transparency. A knowledge calendar should not ask readers to trust vague claims because they sound plausible. The Calendar 5.0 standard deliberately puts primary sources near the claims they support and distinguishes evidence from NDF's interpretation. That approach is itself an information-access practice.
The wider UNESCO/UN history prevents us from making the day about neurodiversity alone. Access to information is a democratic and human-rights issue. NDF's contribution is to show that cognitive and communication accessibility belong inside that wider promise of universality.
That standard matters especially when decisions affect support, rights or participation: usable information is part of meaningful agency, not a decorative extra.
