I am always looking for new great authors to read and will soon finish up one author and will start looking for new authors.  I have never found any web site to be too helpful in finding new authors.  Currently I use Amazon, Borders and Barns and Nobles to help screen the field of books down to a manageable level.  Fictfact has been somewhat helpful, although the site seems to stick to the most popular authors and I have a tendency to go of the beaten path in search of great lesser known authors.  

  What web sites do you use to help screen the field of ebooks down to a manageable level?
