You could use a variation of the muenchian method

 <xsl:key match="Title" name="list" use="Author"/>
 <xsl:template match="Store">
  <table>
   <tr>
    <td>Author</td>
    <td>Title</td>
   </tr>
   <!-- instead of applying just to the first element of each group apply to
all -->
   <xsl:apply-templates/>
  </table>
 </xsl:template>
 <xsl:template match="Title">
  <tr>
   <td>
    <!-- display the Author if this is the first element of the group -->
    <xsl:if test="generate-id()=generate-id(key('list',Author))">
     <xsl:apply-templates select="Author"/>
    </xsl:if>
   </td>
   <td>
    <xsl:apply-templates select="Name"/>
   </td>
  </tr>
 </xsl:template>


Hope this helps you.
