Users who depend on Google and Google Scholar to discover IEEE publications should be aware that due to a change in indexing policy at Google, the majority of IEEE articles have disappeared from Google search results. IEEE has posted the following information regarding the problem:
“Recently we at IEEE discovered something about our IEEE Xplore usage patterns that we want to pass on to you.
We learned that the majority of IEEE Xplore article metadata records had been eliminated from Google search results. This means that anyone attempting to search for IEEE articles by using Google or Google Scholar would be less likely to find IEEE content…
In investigating the current issue, we learned that Google had changed its indexing policy regarding IEEE Xplore. In April 2010, Google decided to discard their previous IEEE Xplore metadata index and completely rebuild an index of over 2.5 million IEEE Xplore metadata records…
We hope that the entirety of IEEE Xplore metadata will soon be discoverable again via Google. In the meantime, we want to remind you that the best way to search IEEE information is to go directly to the IEEE Xplore digital library at www.ieee.org/ieeexplore. With a new version of IEEE Xplore now available with an improved search engine and intuitive new discovery tools, this is truer than ever before.” – IEEE
