Scholarly Impact

Quality and impact are two critical elements of the scholarly record. Research and scholarship is measured by both long-standing and newly developed techniques and tools.

Peer Review

Authors and publishers rely on the peer-review process to evaluate the quality of manuscripts submitted for publication. With the advent of open access, new forms of peer review are emerging.

Quantitative Measures

Statistical tools have been used for many years to gather quantitative data on the impact of scientific and scholarly research. The set of methods and tools used is called bibliometrics. One form of bibliometrics is the analysis of citations.
