Videos on Information Retrieval
If you’re looking for video content to use in courses and workshops on the subject of information retrieval, you might find these two videos made by Jeffrey Beall, metadata librarian at the University of Colorado Denver, to worth taking a look at:

A Little Help, Please
Eric Frierson, a librarian at UT Arlington, mentioned in a blog post recently his library’s efforts to augment databases with sidebars offering assistance. The help provided on the side of this version of ERIC includes an embedded video from Frierson, who, as the education librarian, asks anyone who needs help to contact him or to contact a librarian using the embedded chat widget below the video. The sidebar also provides links to relevant videos:
- “Bad results?” This video teaches you basics of Boolean searching.
- “Where’s the PDF?” Shows you how to use the link resolver button (SFX).
- “I need peer-reviewed.” Demonstrates how to limit results for peer-reviewed articles.
- “How do I cite it?” Explains citation styles.
It’s not clear to me where on the library website you can find these “assisted databases” (as Frierson calls them) or how many augmented interfaces they’ve done for other databases. Still, it’s a very intriguing way to provide instruction at the point of need (on the same page as the search boxes).

Searching via Text to Find Data
Reading this recent interview with Tim Berners-Lee, I was struck by his elegant description of how linked data on the web and textual material on the web (web pages, documents, etc.) will relate to each other:
You’ve got search for text phrases on one side (which is a useful tool) and querying of the data on the other. I think that those things will connect together a lot.
So I think people will search using a search text engine, and find a webpage. On the front of the webpage they’ll find a link to some data, then they’ll browse with a data browser, then they’ll find a pattern which is really interesting, then they’ll make their data system go and find all the things which are like that pattern (which is actually doing a query, but they’ll not realize it), then they’ll be in data mode with tables and doing statistical analysis, and in that statistical analysis they’ll find an interesting object which has a home page, and they’ll click on that, and go to a homepage and be back on the Web again.
So the web of linked data and the web of documents actually connect in both directions, with links.
