2. Raw data available
Evergreen: raw sql queries on entire catalogue data - MARC, circulation, item/location info
Ebooks included in catalogue but hard to match ISBNs, etc.
Circulation data in system back to June 2008; due date stickers before that
No money for GreenGlass.
Goals:
Shelf space!
Remove embarrassingly out-of-date books:

3. Weeding targets Different rounds for different purposes
Low hanging fruit:
Duplicate copies with little recent use
Older editions with little recent use
More painful but necessary:
Older books with no recent use

4. Sample spreadsheet raw data
Multiple editions:
Circulation activity, June 2008+:
This report doubles as a shelf list for librarians to manually skim for out-of-date content titles

5. Manual selection versus heuristics
Different approaches for different weeding targets:
Manual for out-of-date content
Manual for multiple editions
Heuristics for large scale weeding based on age/circ activity
Difficult decision: when is librarian discretion necessary versus cost of librarian time?

6. Example of heuristics
