Classify is a new service from OCLC which returns class numbers (Dewey, LC, and National Library of Medicine) assigned to books in WorldCat. This could be a good way to use the “wisdom of the crowd” when you are not 100% sure where to group a particular book.

I noticed that the url had a “2″ at the end, so I removed it to see what would happen. It appears to be an earlier version of the service. I didn’t have any luck with the first few ISBNs I entered, but the example links work well.

Any other changes to the url bounce the user to the DeweyBrowser, which is a lookup service from a couple of years back. Although it also has a “2″ at the end of the url, nothing happens when one changes it. So much for rewarding curiosity

WebWISER is an online access point for WISER, which stands for Wireless Information Sytem for Emergency Responders.  This database of information on hazardous materials is maintained by the National Library of Medicine, and can be used to both find information on known materials, as well as to assist in identifying unknown materials.

WISER is designed to provide Emergency Responders, such as Police, Fire, and Medical personnel, quick information about a wide range of chemicals and their dangers.  Mobile phones, pdas, computers, and the internet can all be used to access the database.

Not only is WISER in its various flavors a great site for reference questions, it should be a part of any organization’s disaster plan, and people should be prepared so they can access it whenever the need arises.  A tutorial is also available.

You don’t need to be searching for toxic substances (I tried a search for Aloe and got some interesting results) when using the National Library of Medicine’s Toxnet, but if you need to find info and articles on chemicals and such, this would be a good place to search.
