This is a popular research topic. I really hope you kill out there, because a country can't get enough of cool small businesses. Our broad book and DVD categories include entrepreneurship and new business enterprises.
More specifically, we have this great book How To Start a Business in Texas (we have other states too). It tells you all the legal procedures and ways to get help.
In addition, we have a ton of great books that specifically address how to run specific businesses. You can always do a keyword search in our catalog, but we also have a pretty good series from Entrepreneur Magazine. Those books are great because they give you a lot of specific information about profit per square feet, numbers of employees you must hire, equipment purchases, taxes, location, and utility bills, among other information.
Of course, you can always type in key words and see what you get.
I should also recommend ABI Inform and InfoTrac Small Business Collection. These are full of real life articles about nuts and bolts issues affecting small businesses.
Don't forget to research your market! Another good link for that is Local Market Analyst, which breaks down consumer demographics and psychographics by region.
Finally, the Small Business Administration has a useful site.
