PDF USAGE HAS STRONGER CORRELATION WITH CITATIONS THAN HTML USAGE
BASED ON SPRINGER EXAMPLE… 1. Springer: Usage = Total usage- Look Inside • Others*: Usage= PDF + 15% HTML??? *Others: the ones that present HTML fulltext automatically

OTHER AREAS TO EXPLORE • Literature review, environmental scan • More analysis on citation and usage correlation • More evidences on how article types are related to usage in different format • How to adjust usage data based on findings? Will journal ranking change based on adjusted usage?
