At present I am editing a novel ! wrote three years ago and recently I went off to do a little research in the area where the house my character lives in is set. I had to clear up a few things that looking online doesn't really sort out. If the place you set a short or novel in is made up then you don't have to worry about this. However, if you set your piece in a real village, town or city then you need to get certain facts right. Of course the writer does have licence to alter some facts to suit the story, but otherwise it is great to have some first hand knowledge of the place you are setting your story in.
This time (because the house is most important) I have floorplans and have enjoyed placing the furniture on the plans! In fact it is so easy to get carried away with the research that it can interfere with the writing. I find I go off in all directions when I find something of interest which probably has nothing to do with the story.
Taking photos when out on location is essential. That's no hardship for me as I love taking photos. It's another thing I get carried away with it.
Wishing you all a very HAPPY NEW YEAR and I hope you will join me again in the next.
