Research is absolutely key to the success of your book. Why? Because somebody, somewhere will know what you don’t and if you get your information wrong, you will lose a reader. I once read of the ‘stink of carbon monoxide’, whereas it is odourless. I’ve never read another book by that author.
So, the watchword with research is get it right and go the extra mile to make sure it’s right.
Google Earth/Maps where you can “travel” along the roads your book takes place in. Yes, it may be a few years out of date, but not many.
If you would like to explore internet resources, I have included links below, but also a link to my own book, gleaned from over 30 years experience as an information professional and over 20 years searching the Internet. You can find my book here.
