Have you ever worked on a literature review, going from database to database, repeating some searches while forgetting to try additional keywords in some of them when you think of them at a later point in your review? This is the reason I recently Tweeted about a Method of Inquiry Table. This tool, which can be adjusted as needed based on the research, is a simple table that allows you to track databases, keywords, and results. To help remain focused, it has a space for the research purpose and questions.
Seems like such a simple tool, though before I started using one, I always duplicated my efforts while forgetting things along the way.
I uploaded the tool I use here for anybody who may want to use or improve upon it.
