Done it. Thanks a million Jeni, I've said it before and I'll
say it again!

solution below:

  <xsl:template match="adventure">
    <h1>Adventure</h1>

    <xsl:call-template name="alphabetical">
      <xsl:with-param name="section" select="generate-id(.)"/>
    </xsl:call-template>
  </xsl:template>

Calls your alphabetical, with id.
key as you described: Why the space I wonder.

<xsl:key name="auth" match="adventure/r"
         use="concat(generate-id(..), ' ', Ra/lett)" />


The bit of Jeni genius,

 <!-- context is adventure (or other category). -->
<xsl:template name="alphabetical">
  <xsl:param name="section" select="'none'"/>
  <xsl:param name="alphabet" select="'abcdefghijklmnopqrstuvwxyz'" />
  <xsl:if test="$alphabet != ''">
    <xsl:variable name="letter"
                  select="substring($alphabet, 1, 1)" />
  <xsl:variable name="auths"
    select="key('auth', concat($section, ' ', $letter))" />
    
    <xsl:choose>
      <xsl:when test="$auths">
         <xsl:apply-templates select="$auths[1]"/>
      </xsl:when>
      <xsl:otherwise>
  <h2>The letter <xsl:value-of select="translate($letter, $l,$u)"/> </h2>
        <p>
          There are no authors beginning with
          <xsl:value-of select="$letter" />
        </p>
      </xsl:otherwise>
    </xsl:choose>
    
    <xsl:call-template name="alphabetical">
      <xsl:with-param name="alphabet"
                      select="substring($alphabet, 2)" />
        <xsl:with-param name="section" select="$section"/>
    </xsl:call-template>
  </xsl:if>
</xsl:template>


Processing for first r record.

<xsl:variable name="u" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/>
<xsl:variable name="l" select="'abcdefghijklmnopqrstuvwxyz'"/>


 <!-- Template for the first record in a letter -->
<xsl:template match="r">
....
 <xsl:apply-templates select="following-sibling::r[Ra/au = $thisAu ]" 
 mode="others"/>
</xsl:template/>

<!-- Template for those other than first. -->

<xsl:template match="r" mode="others">


Produces required output:

The letter I
Innes, Hammond. 
Delta Connection. Read by Michael Tudor Barnes, 12hrs 36mins.  TB 11148 
A desperate escape from Romania after the fall of the Ceausescus...a violent
introduction to the new rules of warfare on the borders of
Afghanistan...then an icy struggle for survival amongst the world's highest
mountains. Death follows those who seek beyond the 'Delta Connection' -
searching for something closely guarded in the most dangerous region on
earth. TB 11148 

The letter J
There are no authors beginning with j 

The letter K


with all books by same author under single author title!

I'm happy.

Regards DaveP.
