I just want to share another way to organize information, which is not visible but used in the TOC.

Instead of changing the layer style to invisible, it may be useful to change the style to non-printing.
The advantage is, that you can still see your information, but when creating the PDF, it’s not included. And you don’t have to switch between visible and non-visible every time.
I often use it in Illustrator, but it works in InDesign very well, too.

I hope you can understand what I mean, because english is not very well, a foreign language for me.

Would it be possible to do a “save as” of the entire book once we have finished with ALL tweaking that would affect page layout and then build a different index in each of the books, then add the three generated indices into the original book? In other words, if we don’t “update” the index, could we have three separate indices in one book that were generated by the duplicate books? Thanks.

Unfortunately I’m using a university computer and I don’t have access to CS4. Looks like my solution is to either use CS4 or CS3 with updates. What do you think? Thanks.

Are you running CS3 or CS4? If CS3, which version? Have you been running the automatic updates. I may be grasping at straws here, but Indexing was broken for a time in CS3 and fixed with an interim update.

Sorry for the slow reply, Waine. Shame on me for not getting back to you sooner. Unfortunately, books or individual documents can only have one index. InDesign can’t track more than one. I’m not sure if a plug-in like Sonar Bookends from Virginia Systems can do multiple indexes, but it’s a far better indexing solution than InDesign’s built-in index feature. You had it right when you used the word “painful,” Waine.
