Denis Saulnier, der sich an der Harvard Business School mit E-Learning beschäftigt,  erörtert in seinem Weblog die Vorteile von freier Verschlagwortung im OPAC durch die Benutzer. Es geht ihm insbesondere um die typische Lernsituation an der Hochschule:From a student perspective, there are numerous benefits of social tagging. Access to the universe of material tagged by their peers and professors increases the scope of research and discovery. "Gray literature" -- materials not yet published or peer-reviewed, blog posts, discussion forum entries, ezines, websites, podcasts -- could now be categorized and shared. The use-case would involve a student searching their library resources online and receiving a search results list that first presented "official" findings based on the keywords used in the search but then also presented additional community-generated 'popular' tags for each item.Ultimately proponents argue that this is good for academic research for the same reason it was good for bookmarks and photos -- the chances of finding what you want dramatically increase when you can search the accumulated knowledge of tags created by the community vs. those created by a single, top-down taxonomy. Plus there is the added benefit of being able to classify items with tags related to specific sub-communities -- tagging content with a specific Harvard course identifier, etc.In der - live geführten und danach in den Kommentaren des Weblogs wiedergegebenen - Diskussion in Harvard werden zahlreiche weitere Pro- und Contra-Argumente genannt; eine lohnende Lektüre für alle, die sich näher mit dem Thema beschäftigen.[via Jakob VoÃ?]
