I think you mean: books with multiple titles but with one author

That is quite a generic question. In general, it is probably not needed 
to use xsl:if. And yes, you can use the count function. When you are in 
the context of <book>, you can use count(title) to find out. When you 
design the matching template for <title>, just change it to be 
<xsl:template match="title[1]" to match only the first title and make a 
throw away generic template for the rest.

<!-- first title -->
<xsl:template match="title[1]">
   <p><xsl:apply-templates /></p>
</xsl:template>
<!-- throw away -->
<xsl:template match="title" />

If you don't want to do anything with count, this is it. Alternatively, 
you can simplify matters by changing your select statement instead. But 
that is a matter of taste and context.
