On-line pre-publishing

[gerarus@westnet.com.au]

    One question that I was reminded of in our discussion on the
Neoaves paper by Ericson et al.:
    There's an increasing tendency these days for journals to make
papers pre-available (excuse the potential neologism) on the web
before they actually appear in print. It's a tendency that I
personally am a little suspicious of, mostly because it can increase
confusion about publication date when that's an issue. But my
question is this: Is anyone aware of cases where an article has
actually changed between the available pre-published version and the
final version? I know the journal _Molecular Phylogenetics and
Evolution_ has taken to making the text of articles available as text
documents before the article is even formatted as a pdf. If changes
are made, it could potentially cause quite a bit of confusion...

    Cheers,
