Library Partnership Rating (LPR) is unique in several ways.
LPR is driven by library values associated with openness.
The LPR Rubric, which is used to determine LPR scores, is open.
The LPR Rubric criteria do not evaluate institution-specific agreements. Criteria are limited to publicly available practices and policies that are the same across libraries, institutions, and author agreements.
LPR scores are determined at the publisher level. This is in contrast to journal impact factors, which are, as their name implies, evaluated at the journal level.
While LPR employs library values to evaluate journal publishers, it is important to note that many of the profession’s values are shared by researchers, institutions, and learned societies. LPR Rubric criteria are therefore relevant data points in creating a broader, more complete evaluation of a publisher.
LPR is based on an early idea introduced in an article by Rachel Caldwell. The founders of LPR are Rachel Caldwell (University of Massachusetts Amherst) and Robin Sinn (Iowa State University).
