[Web4lib] Which databases can Google Scholar crawl?

[Even Flood]

One important point I have not seen covered in this debate is how deep
GS is indexing the different sources. It is obvious that for many of
them GS indexes the whole text, including the litterature list, while
from other sources they might just get the bibliograophical details
and the abstract. If I remember correctly, when GS was launched theu
announced that Blackwell and Springer were among the publishers that
allowed deep indexing, while Elsevier did not. So the  Elsevier
content might come from open abstracts databases like Ingenta and, im
many cases, the journals' home pages with no litterature lists, while
the deep indexing comes from a mix of instutional repositories, open
source journals, select publishers ets. Maybe they do not know
themselves exactly what goes into the database. Another issue is the
frequency of the updating which we also know nothing about.
