Reliance on the Internet: Reliance on the Internet: pros and conspros and cons
+ Access to up-to-date materials compared to print
+ Visualizations, simulations, data explorations offer interactivity and alternative learning approaches
+ Access at school and home
- Attribution often lacking or unknown
- No consistent review filter
+/ - Broad range of content
+ lots of STUFF
- narrowing search difficult

Why a digital library?Why a digital library?
• Provide efficient discovery of quality materials
Efficient = easy to find resources using search techniques
Quality = selection criteria for resources
• Provide safe environments and “boundaries” on the web
• Special collections and services • Teaching tips and reviews
• Ed. Standards information
![Page 6: Digital Library Services for Teaching and Learning Holly Devaul Digital Learning Sciences University Corporation for Atmospheric Research](https://reader038.vdocument.in/reader038/viewer/2022103111/551a0dd9550346a4248b4932/html5/thumbnails/6.jpg)

How digital libraries work
• Digital libraries hold metadata records, and sometimes primary content
• Have a defined scope of content, intended audience
• Metadata describes the resource content, the intended user audience, resource type and other characteristics
• Search over metadata and/or primary content to retrieve information about and links to relevant resources
![Page 7: Digital Library Services for Teaching and Learning Holly Devaul Digital Learning Sciences University Corporation for Atmospheric Research](https://reader038.vdocument.in/reader038/viewer/2022103111/551a0dd9550346a4248b4932/html5/thumbnails/7.jpg)

How resources get into DLESE Suggestions from users-
7500 of 13,000 resources
Organizations with many resources create a collection and apply for accessioning as a distinct collection
