Tips for Self Promotion, Sales, and Advertising discussion

The NYROB offers an Independent Press Listing (complete with a 4 color reproduction of your book cover) for about $300 an issue. It is also listed on their website. A nice place to be seen if you can fit it into your budget!

I desperately need help in advertising my books. They are:
Blessed Are the Merciful
A Healing Place
Texon Gold
My website is blessedarethemerciful.net
I just read about book parties in Writers Magazine. They explained some ideas, but my books have all been about WWII in the Philippines. I need help selling my book. I have tried everything possible.
Can someone out there give me an idea for putting on a Writer's book party. Where could I hold it? How could I theme it? I just don't know where it would help me, but it helped the author of the magazine article. I'm interested in WWII and can't seem to write sci-fi, which is the big thing nowadays.
Any advice would be well received. Thank you so much.
