It is a digital record of American history and creativity. These materials, from the collections of the Library of Congress and other institutions, chronicle historical events, people, places, and ideas that continue to shape America, serving the public as a resource for education and lifelong learning.”

Why is this recommended as a controlled vocabulary field?

Your turn

• Your design for your DL is due now.• Each team, present your DL plan to the rest

of the class for comment and suggestions.– Use the plan you submitted. Take a few minutes

now to decide who will do what in presenting it.

• This is both a review of the planning you have done and a chance to learn from what others are doing.

Tonight

• Further detail of Dublin Core

• Look at another DL

• Google Books example

• Student status on DL

Next Week

• Access management and security– Read: Arms Digital Libraries Chapter 7

“Access management and security” – Read NINCH Guide Chapter 4 “Rights

Management”– Note similarities and any differences in

approach or philosophy

• Demonstrate your working DL
