## Makes a Corsortial Contribution

- Although other libraries lack the link to the online version, they benefit from the University of Denver link.

## Hidden Internet Mining

- Hidden Internet / Deep Web:
- Not accessible to search engines
- Often rich in content
- Est. size: 500x “surface Web”

## Hidden Internet Mining

- Examples of mining places:
- NEPIS  http://www.epa.gov/nepis/
- NCJRS  http://www.ncjrs.org/
- DOE Information Bridge  http://www.osti.gov/bridge/
- Numerous Others
