Help is on the way…

COUNTER Code of Practice for e-resources

Release 4, April 2012

Still two Book Reports, still no standard definition of “section”

Clarification of ”section” in Book report 2 “The Section Type (Chapter, encyclopaedia entry, etc.)

used in this report must be indicated in the report itself”

Vendors have until December 2013 to comply

Libraries and statistics

Raise awareness among librarians

Explain our needs and demands to vendors

New metrics for evaluation?

What do we want to build?

Thank you!
