I suppose it depends on what those multi-page "articles" contain. I'm always interested in getting as many pages in the index as I can, but pagination that is generated in an automated fashion can be seen as near-duplicate and fodder for the supplemental index. I still think that's better than not being in the index at all.
I like to give page 2, 3 etc unique titles and descriptions. Sometimes I will precede the title words with a numeral 2. and so on as a usability feature for the human visitor - but not always.
From what I've seen, it depends on how deep the pagination goes. I ran a similar question to this by Matt Cutts a couple months ago and he said something along the lines of it being good if there are noticeable issues with duplicate content or if it's more important for the user to land on the first page of the paginated pages.
Personnally, I don't do index for paginated pages - The main issue being duplicate content.
Another thing not to forget is that indexing paginated page is not really user friendly... Example - User do a search in search engine, find an item (e.g. page 5), click on the link, can not find the item (because it is now in page 7).
As AZEvil said, I prefer my user to land on page 1 and only index page 1, 2 and 3 - not further.
