Early citation advantage?

[Loet Leydesdorff]

I remember a paper by Grant Lewison in which he showed that papers from
projects funded by the European Commission peaked earlier in the citation
window because they were circulating in the projects before being published.
However, it did not change the total citations in that case. Perhaps, it
does with OA, but the effects may be also field-dependent.

With best wishes,  Loet
