Compliments of @acrolaw on Twitter, I was directed to an excellent blog post entitled Making the Switch to Digital: Legal Research.  The article, posted by Delaware Employment Law Blog, includes some good advice about getting the most out of your online research and information management with Adobe Acrobat 9.  While I wouldn't necessarily implement all of the tips for myself, there is certainly some value in creating a pdf repository of authority used in research, particularly if you've ever considered creating a fully indexed e-brief.  I've seen one such brief, with each citation linked to accompanying authority, and its a thing of beauty.
