When I wrote my Regencies, I had an entire bookcase (not just a bookshelf, but a bookcase) dedicated to my time period. You'll find notebooks upon notebooks of notes and printouts on the time period. I have books on the Napoleonic Wars, on the English monarchy, on culture, villages, music, clothes -- you name it, I have it.
I enjoy the research. However, now that I'm no longer writing in that time period, I haven't been making much use of that particular bookcase.
I tried my hand at writing a contemporary once, thinking it'll be a breeze because I won't have to do so much research. Boy was I wrong! I can honestly say without a doubt that writing a contemporary is harder than writing a historical because of the research involved.
You're looking at a sub-genre where things are more easily recognized by readers. Don't know a thing about yachts? You better do more than just the usual book and internet search. You need to take a trip to see one in person and talk to some people who specialize in it because you bet some reader will read your book and KNOW that you didn't do your research correctly.
What I find most difficult about researching 21st century things is that there isn't much written about it in books and on the internet. Not like there is when dealing with historical facts. Information isn't readily available because it's automatically assumed that people are already familiar with the subject, and if not, then they can have easy access to see it in person and ask questions.
My hats off to contemporary writers!
Hate research? Then I suggest trying your hand at writing fantasy. Sure, there is some world-building involved, but EVERYTHING can be made up. Give it a shot! You might be surprised at how much fun it is to really and truly make everything up.
Whatever your take on research, we can agree that researching is an important part of writing.
