I'm just wondering if anyone has any advice. I'm finishing up the proofing of a non-fiction book I wrote and am looking to mostly use this to build credibility.

If I sell a few copies, that's definitely a bonus, but it's not my primary objective - I just want it to be 'out there' for people to see that I'm an author (I plan to combine it with other programs/products online).

Originally I was going to go with Lulu for this, but then someone else was mentioning the Amazon self-publish program. What would be best for me? I'd like to keep my costs as low as possible in all this. I want the book to be on Amazon, but if it was able to get online on other sites, that'd be even better.

Any thoughts would be appreciated.
