I guess for perhaps a faster fix you'd need a merge feature that will join all of the individual indd files into one, then you could use the publish online feature. alternately, you would have an editing option in the publish online feature to add pages or allow online publication of a pdf or epub created through indesign. this is a great feature, as is the indb feature. It's a shame they don't work together. The online publish allows me to control access and prevent piracy. The indb allows me to work with smaller files and finish faster . without jamming up my computer, with lots of other features. please fast-track this capability!

Please add this feauture!

MEANWHILE, the solution I found, it's to save the book as a pdf.

Open a new document, and use this script

You don't need to download the script, as it's adobe.
Adobe Script, “PlaceMultiPagePDF.applescript”

Add the pdf and publish the file!

We have sort of a catolouge with diffrent themes, and they are made in diffrent documents, so that the file isn't to big. Then it is combined to a book in indesign. But then we cant use the publish online.
Can you please make this possible.

Hi guys! How many voices do you need to hear to incorporate this feature in some way into Indesign. Just let us know. We will collect them. It is question of cloud disc space due to big files expected? Why is there no reply from responsible man after four years of publishing? Thank you.

So, how can I upload my multiple ind documments?

This is needed... 100%. Really surprising it hasn't been implemented yet.

Please, guys. We need that. Make it possible, please.

I need this feature!

Publish Online to Books. please!!!

One vote from here too!

Please extend Publish Online to Books.

This would be a great feature that saves me a lot of time!

I didn't know this WASN'T an option for books. : (

I guess I will combine the book into 1 ID file as a workaround.

This would be really beneficial, especially for collaborative projects. My team breaks up sections that come together as chapters, so the indd documents alone are too small of chunks to publish separately. I would also love to be able to publish online existing pdf documents (since sometimes we re-organize pages after export).

Yes, please please please!

I agree it would be a good option if you could publish online an Indesign book with several chapters. I vote for it so that they take it into account for the future.

Oui je suis d'accord avec ça !

+1

Would save me a lot of work!!!

Yesssssss!

My long textbook is segmented into a book. Publish online allows me to share the latest build of the book during the review process with a nice flip spreads UI. Right now I combined the book into 1 ID file and its cumbersome as a workaround. Let's get more people to vote on this! Share in your network of CC creators.
