I recall seeing an Adobe online publication some while ago that was devoted to accessibility in InDesign. Of course, I can't find it again. Does anyone have a link?

Accessibility is more complex than what you'll learn from an online reference, even mine.

Example, my live online class is 16 hours long and I wish I had about 4 more for my students so we can get into some more complex design issues.

But to narrow accessible PDFs down to the essentials:

Everything in the document must tagged, even it's an artifact (which is am attribute on the Figure tag).
Each element must have the correct tag that identifies its purpose and context. Examples: H1 - H6 for headings, Note for footnotes.
The PDF's Tag Tree must have a logical Tag reading order.
The PDF's architectural reading order (the Order panel) must also be logical.
All graphics must either have appropriate Alt Text or are artifacted.
All hyperlinks must be accessible hyperlinks. Includes: cross references, index entries, TOCs, URLs, and email addresses.

There are more requirements and accessibility features to meet PDF/UA and WCAG accessibility standards, but these 6 items are the foundation that must be there for all PDFs to be usable and accessible for the majority of users.

I notice that your note seems to refer only to Acrobat, which I sort of understand, I am sort of hoping to do some of the work in InDesign. For instance I have a repeating graphic logo on every page, which should be an artifact. Can I tag and export it as such in InDesign?

Good strategy, but make it easier on yourself <grin>.

Any time the page count goes beyond 100, we consider breaking it into logical sections and use InDesign's Book utility to manage them (and export 1 PDF from all of them, and make one TOC from all of them). You're really asking for problems when one INDD file is 500 pages!

1. Break up the one long INDD file into several. Whatever makes sense, like at chapters or major sections.

2. If it's all threaded together, you might need to use the Break Thread script:

—Window / Utilities / Scripts to bring up the panel.

—In the Community folder, choose BreakTextThread.jsx and follow the instructions.

3. Create a new "book" (File / New / Book) and then drag the individual INDD files in order into the panel.

4. View the Online Helpx for books at https://helpx.adobe.com/indesign/using/creating-book-files.html to learn how to control pagination between the files, export one PDF from the files, and more tasks.

As long as you make one PDF from the book, accessibility should be just fine. Your other method, combining the files individually in Acrobat, is a royal PITA hot mess of work.

Remember, to meet the PDF/UA-1 accessibility standards, you must have a live TOC in any PDF that is 10 pages or longer, as well as Acrobat Bookmarks in the bookmarks panel. You won't get that and their correct hyperlinks if you piece the files together in Acrobat.

So, yes, break it up into smaller sections. Use the Book utility to manage everything.

Dear Bevi, apologies for jumping on this tread.

In light of your awesome explanation above, could I assume that the reading order will be stablished by the order that the files are organised in a book?

I have a 26 files (chapters) book file created and need to make it accessible, do I need to create Articles within each file (chapter) and then when exporting the single book pdf it will take trhe order from there + specific chapter order from articles?

Sorry, very wordy and convoluted, just want to make sure I explain it correctly.

Thank you so much in advance.
