OpenOffice.org for Dummies
$24.99
I was very disappointed in the OpenOffice for Dummies. I was specifically looking for the "Base" portion of OpenOffice and it was not mentioned at all.

I also purchased OpenOffice 3 and the information I wanted was included, although not in as friendly text as I expected the Dummies to be.

I'm very happy with the purchase. I'm new to OpenOffice but I really love it! I hope to see more books for open source programs, especially programs that rival Microsoft products. Thanks.

[...] is a great product and in my opinion way better then MS Office.
Don't be mislead by the reviews here. If you read them you'll see that the complaints at on the seller and not the product. The poor scores should not be here, they should be on the sellers scores.

Now, on another note, [...] is FREE SOFTWARE. They are allowed to sell it to you, but you can download it legally for free at [...]

If you don't want to download it you can buy it from here. I just wanted to make it clear that you don't have to pay for it. It is free and Open-Source.
