Where can I get a free extension for Adobe's latest PDF reader that allows me to actually highlight information I'm reading and save it?

here: http://www.adobe.com/products/acrobat/readstep2.html

it is version 8.1

it allowed highlighting, copying and you can paste it elsewhere (eg word)

if you want to edit the PDF you will need Acrobat Writer (http://www.adobe.com/products/acrobatpro/acrobatstd.html)
its only 300$ :shrug:
