Finding info on the internet, in books, and even TV and movies are ways in which I research. Since part of my current project takes place during the Civil War, I find myself searching the web a lot. Sometimes I loose myself in the vortex of information; reading things that may not pertain totally, but are interesting nonetheless until I find and hour or more has gone by.
I've been thinking of taking an afternoon, lounging in sweats, eating snacks and renting current movies set during the Civil War. It would help me imagine what they wore, how they talked, etc. and it might inspire me. If nothing else, it sounds like a good excuse to relax. I also plan on visiting Virginia again hopefully soon, a plethora of information is there and writing while actually being there could help me get into the characters.
I also research on the art of writing. I wish I could devote more time right now to this because I know I have a lot to learn. I have some books I refer to often. One that I'm reading right now and would recommend is "Keys to Great Writing" by Stephen Wilbers. Websites like SCBWI.org and CBIClubhouse.com are also helpful for researching writing techniques. My favorite way to research writing is reading books in the genre I'd like to become proficient in. The only drawback I have though is when the book is good I find myself engaged in the plot and forget to concentrate on things the author has done well, and things I should avoid. In general when it comes to any research I have to find good ways to help my brain retain all of this info, so when it comes time to use it, I'll remember it. I guess good organization should be considered when researching.
