1. The impact of knowledge
exports from librarianship and
information science (LIS)
Investigating cross-disciplinary citations

2. What is the external influence of the
interdisciplinary field of LIS?

3. Identifying exports to other
subject areas

5. Patterns in the results – citing journals
• Dominance of science subject
areas
• Bulk exports from single articles,
authors or institutions
• Single citations from very high
impact journals Genuine impact =
High citation count x
impact factor
Citations to a range of
LIS research

6. Patterns in the results – cited journals
LIS journals v. non-LIS journals
•Non-LIS = higher citation counts
•Non-LIS = higher % above average
impact factors
•Differing subject destinations for
exports
Publication of LIS
research in non-LIS
journals leads to higher
impact exports

8. Implications
• Exported knowledge achieving significant
influence
• Pre-publication export to maximise impact?
• Impact factors, once normalised, are an
effective means of quantifying export
value
• Using author to assign disciplinarity can
be misleading
