Reasons for citing...
1. Paying homage to pioneers.
2. Giving credit for related work (homage to peers).
3. Identifying methodology, equipment, etc.
4. Providing background reading.
5. Correcting one's own work.
6. Correcting the work of others.
7. Criticizing previous work.
8. Substantiating claims.
9. Alerting to forthcoming work.
10.Providing leads to poorly disseminated, poorly indexed, or uncited work.
11.Identifying original publications in which an idea or concept was discussed.
12.Identifying original publications or other work describing an eponymic concept or term.
13.Disclaiming work or ideas of others (negative claims).
14.Disputing priority claims of others (negative homage).Eugene Garfield / F. Osareh Libri 1996, 46, 149

Quality judgements in the publishing process
•Before publishing – the peer review process
•After publishing – usage (citations, downloads etc)
www.gu.se
Research evaluation indicators
• Productivity (number of publications, number of collaborators)
• Demand, impact, “quality” (number of publications in quality channels, number of citations)
• Excellence (compared to the field, ratio top5% cited publications)

Research evaluation indicators
• Productivity (number of publications, number of collaborators, …)• Demand, Impact, Quality (number of citations, number of publications
in quality channels, …)• Excellence (compared to the field, ratio top5% cited publications)• Collaboration (network properties estimated by co-authorships)• Internationalization (number of publications in international
journals, number of international collaborators)• Interdisciplinarity (number of publications in channels in other
fields or with co-authors from other fields)
www.gu.se
• Publications in the database Web of Science (WoS) are aggregated for each university
• Number of publications and number of citations to the publications are normalized and multiplied together to form the publication indicator

Conclusion
• Compare ”like with like”
• Fractionalizing etc
• Knowledge about the organisation analysed
• Evaluating the past
• Conflict of interest
• Incentives? Research policy
