By the way, is it just me, or does the new PubReader format on NIH PubMedCentral totally kick butt? I can't help but wonder why journals have not gone to something like that. The best thing is that you can quickly glance at a figure–any figure–rapidly by just hovering quickly over the figure thumbnails at the bottom of the page. You read, see a reference to a figure, and can quickly take a peek (and then quickly come back). Why it took somebody 15 years to do something like this is anyone's guess, but I sure am grateful somebody finally did it.
Oh, and the best part is that it's open access! These are the free versions of the articles you have to submit to PubMedCentral.
