Type in anything that interests you into PubMed’s free database access and spend some blissful time pouring through academic full text articles that are free for anyone on a computer.

Google Reader – using an RSS reader is liking hooking yourself up to a information IV and you pick what sites go in the bag. Seriously, why waste your time, get your list of headlines and go from there.

Use Delicious.com to bookmark all your favs (add a tag to make them searchable). This makes expanding your horizon online feasible, retrievable, organizable from any computer.

Write your docs on GoogleDocs and they will back it up for you. For me it is very helpful to access all the folders of docs from anywhere.

Great tool for training and answering reference questions – Jing allows you to create a short video of your mouse moving on your computer screen and gives you a URL to paste; 2 gigs are free, and there are plenty of other options.

Lastly pandora.com will create and play ad-free “radio” stations for you – great way to expand your music enjoyment.
