Dear colleagues,
I checked the effect for the set which I can assess most easily and that is
for my own papers. Five full articles from the past have now been converted
into "Proceedings Papers". Among these two articles were from
Scientometrics:
Title: Scientometrics and communication theory: Towards theoretically
informed indicators
Author(s): Leydesdorff L, VandenBesselaar P
Source: SCIENTOMETRICS Volume: 38 Issue: 1 Pages: 155-174 Published:
JAN 1997
Times Cited: 15
Title: THE DELINEATION OF SPECIALITIES IN TERMS OF JOURNALS USING THE
DYNAMIC JOURNAL SET OF THE SCI
Author(s): LEYDESDORFF L, COZZENS SE
Source: SCIENTOMETRICS Volume: 26 Issue: 1 Pages: 135-156 Published:
JAN 1993
Times Cited: 17
These two papers were not proceedings papers. I have no idea why their
status was changed. The other three papers were also not Proceedings papers.
Best wishes,
Loet
