I am constantly adding new resources to my over 1,700 categorized “Best Lists.

I also regularly “cull” through the lists to weed-out dead links, but haven’t been very systematic about doing that task.

So, I’ve started to go through them and highlight the ones that I’ve gotten around to completely cleaning-up and revising. I’ve completed this process well over 300 lists over the past eighteen months.

Here are a list of them from this month (you can see previous compilations here):

The Best Places To Get Royalty-Free Music & Sound Effects

The Best Sites To Learn About The Apollo 11 Moon Landing

The Best Ways To Back-Up Your Computer & Online Work

The Best Resources For Finding And Creating Virtual Field Trips

The Best Sites For Learning About Yosemite & Other U.S. National Parks

The Best Websites For Learning & Teaching Geography

The Best Online Games Students Can Play In Private Virtual “Rooms”
