Sales rank of my book.

Very briefly(1-2 days ago), the sales rank for my book- "E-Commerce Management: Text and Cases" on Amazon.com was in the thirty thousands. Today, it is back to 110,000 or so. Has Amazon started to include used book sales in its salesrank? I wonder.

Four ways in which Google Scholar must improve.

Here are Prof. Sandeep Krishnamurthy's ten unsolicited suggestions for the improvement of Google Scholar-

1> Create an advanced search feature that allows visitors to limit searches by publication type,
date of publication and type of publication.
2> Include Google Scholar links when people search on the main Google page. This is already being done with Google News.
3> Create a Google Scholar alert similar to Google News.
4> Provide zeitgest data on the most common searches similar to what is being done with Froogle (we academics would love this).
