This might be old news, but I just came across a free organizational platform called Trello: https://trello.com
The company is a New York based software company that also creates other software (which is not pitched or promoted on Trello) but covers the costs of Trello which is why it's free.
Anyways, I just wanted to share this since I've used a variety of tools in my business (Basecamp, To-Do apps on my iPhone etc.) but I really like the simplicity that Trello brings to the table.
There's the typical browser access (similar to Evernote) but there's also iPhone/iPad apps as well as Android.
Can be used by teams, or just privately.
I'm using it to not only keep track of marketing courses and books I'm reading, but also prospects I come across, free content ideas I think up mid-day that I can follow up on and create later etc.
I only recently came across this resource myself recently, but who knows how long it's been out, so I figure I'd spread the word.
Use it. Don't use it. Doesn't matter to me, but thought you should know.
