The “Import into WebLearn” link disappeared from the Google Scholar interface with WebLearn’s Reading List tool some time during last week (17-21 May 2010).
According to Google, this problem was caused by a failure when Google’s crawler last tried to retrieve the registry of Sakai ‘Citations Helper’ implementations from sakaiproject.org. Unfortunately, they also report that it won’t be fixed until sometime this week (24 May 2010) when Google next crawls sakaiproject.org.
The Sakaibrary team plan to work with Google to try to find a better solution for hosting this registry so that this problem won’t happen again.
