Just recently I saw a comment from a fellow genealogist, although I cannot recall who, where they stated that they kept a writing portfolio.
Over the years I have kept a list of what has been published, where and when – you can see the list HERE. I also tend to keep a copy of the article, presentation, or proposal that is used or written originally. I often give the same presentation to different groups, although the presentation might be titled the same, the content is potentially different, with links and resources up to date.
I would be interested to hear your thoughts on whether I should keep a copy of the printed article, either physically or digitally?
