..........the can keep track of all the things to do in this game? I am playing on a PS3 and do not mind keeping a checklist by hand. So many things to keep track of:

Books
Quests
Items
Houses
Unique Items
Etc....

If anyone knows of one (an app would be fantastic), please let me know. I will greatly appreciate it.

I call those a Notebook and the UESP Wiki.

If you buy the official guide, it has everything from the base game. You would have to take notes for any of the DLC. It's a bit more organized than using the UESP and a notebook, at least for the base stuff. Plus they have little checkboxes.

I never use the guide for questing but once I've invested roughly 1000-1500 hours into the game, I start peeking at the unique items list and see what I missed and generally how to obtain it, but never the specifics.

I know how you feel.

Sometimes it can be overwhelming... "do I have this book already?"

But it should be pretty easy to find lists of things like books.
Here's the UESP Wiki entry for all books...

So just copy pasta that to a clean Word page, edit as and if you desire, print it and there's your book checklist.
Rinse and repeat for everything else you want.

...or as Darksun mentioned, buy the official guide to be super organized... it looks like a nice volume although I rarely use them myself.
