I just spoke to someone (unpublished) who told me she ran out of printer ink while printing out some online research she was doing in preparation to write a nonfiction book. That strikes me as strange. I've been a heavy computer user since 1990 and actually prefer to see things on a computer screen. If online information is time-sensitive, I might copy and paste it into a document on my hard drive, but if it's always going to be available, I just bookmark where I found it in case I need to refer to it again. Otherwise, I use MS Word to take notes on it and put my ideas down. I don't even follow the recommended practice of carrying a pocket steno pad and a pen when I'm away from my desk in order to jot down ideas as they come to me, simply because handwriting things is not part of my nature. How about you? Do you prefer to review your research documents in electronic form or hardcopy form? If the latter, do you actually print out online material and then review the hardcopy?
