  • Hi everybody. My name is Julia Remick and I am an Information Scientist with Yellow Book USA. I should put out a disclaimer before I begin that I am notoriously incoherent when talking about our taxonomy to people who aren’t immediately familiar with it. But I did show this presentation to a few people beforehand this time, so hopefully, I’m somewhat intelligible. Also, the 3 speakers before me had all the hard work and did such an outstanding job explaining their ideas and experiences with taxonomies, so my job should be easy. We’ll see!

      • A “growing season”
    • Possible solution: taxonomy-directed folksonomy
