I know some people aren't into self-publishing - you lose the benefit of an editor, etc, but I'm a big fan of it in principle - I've just never had cause to practise it. To my mind, self publishing gives power to the indiviudal in the same way that blogging does.

If you haven't looked at it already, may I suggest you have a gander at Lulu. It allows you to print on demand (POD) - so everytime someone purchases a book it gets printed and sent to them. I think this is a bit more expensive per item than traditional printing, but you don't have to worry about the cost of an initial print run. There are other POD providers, but I don't whther they are beter or worse than Lulu.

And as for editorial input, I'm sure that members here at Perlmonks would only be too happy to provide helpful feedback - especially since your book would intrigue a good number of them
