I think I used a thesauri once or twice in college….back when we had to do our research in the library with physical materials, not on a computer. I remember thinking it was quite useful, this book of terms, had it been there all along? Then computers took off, and databases, and online search capabilities. I don’t think I’ve consulted one since then, although I believe I’ve encountered them online (when the site responds to my misspelled search with, “did you mean xxxx?”). Its easy to be unaware of the existence of a controlled vocabulary or thesauri online when the site automatically applies it, making suggestions and correcting or suggesting terms. I wonder how many researchers purposefully consult such sources? Or if it doesn’t matter, when online searching seems to apply them whenever a search is performed? The tutorial on constructing thesauri demonstrated how much detail and thought must go into creating these tools that many are so unaware of!
