"old_expat -- Unless you already have an overabundance of levels on the site, the examples you gave seem as if they'd work well if there was a main page with links to pages one level down. Your "more on page 2" idea, but with just enough about a topic on the main page to whet some interest, then a link to the rest of the article/information."
I'm thinking that this issue may be one of the "Top XX" things that makes a site good .. from several points of view.
1 - It gets a number of subjects on a given topic in front of the user's eyes.
2 - It allows a fair degree of flexibility
3 - It *sort of* acts as a sub-sub menu .. or a secondary form of navigation.
"The breadcrumb-type navigation WebmasterWorld uses at the top of these pages could help the reader keep track of what main section they're in."
I have to admit to being a dummy in knowing how to integrate this into my site in some "automated" fashion. My site suffers from lots of "I didn't plan well" issues .. because it started as a "hobby" site and is about 10X larger than I originally planned for it to be.
As an example, about 70% of my pages are .htm and 30% are .php
"Sometimes the need for more pages comes along without you planning for it. What was originally one page on my website is now a main page with links to "more" on 29 others. (And when I add a page of new info, I put a bright red "New!" next to its lead on the main page for about a month.)"
None of the pages I'm fussing over right now have quite than many, but there are several that can be broken into 2, 3 or 4 pages.
Very honestly .. in many cases, the reason I put so much on one page is because of the menu system I was using. I simply didn't have room for the number of items I should have had on the side menu.
The things I'm trying to decide related to this are:
1 - How much is too much.
2 - How much is not enough.
In one or 2 cases, if I went by an absolute standard, I would break one page into 3 logical items .. and the first 2 pages would be fine .. but the third page would only be 1/2 - 3/4 of a screen.
