[QUOTE=Shimarenda;1455684...As one who works in a library cataloging department, it both amuses and concerns me to watch IT professionals and web theorists discuss countering the prodigality of tagging with the invention some sort of controlled vocabulary to indicate the subject of an item. I seriously can't tell if they are aware of subject headings or not since they they talk like they have discovered some new concept.[/QUOTE]
But on the other hand, it's going to be so much fun watching them make all the same old mistakes that we were taught to avoid in library school
Fwiw, being an ex-cataloguer myself, I've established a very sparse & simple tagging vocabulary for my Calibre library - it can always be expanded over time!
