Okay, then how's this for a recipe to create rich linked data of  
electronic books and authors within my own site as well as to the  
outside world:

   1. Mint URIs pointing to representations of local etexts
   2. Mint URIs pointing to representations of authors of local etexts

   3. In resources of etexts, include owl:sameAs links to DBpedia  
resources
   4. In resources of etexts, point to local URIs of authors

   5. In resources of authors, include owl:sameAs links to DBpedia  
resources
   6. In resources of authors, include owl:creatorOf links to local  
etexts

   7. For extra credit, do the same thing for subjects/keywords

For example, the following resource descriptions:

<!-- etext #1; points to local author and remote title -->
<rdf:RDF
   xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
   xmlns:dcterms="http://purl.org/dc/terms/"
   xmlns:owl="http://www.w3.org/2002/07/owl#">
   <rdf:Description
     rdf:about="http://infomotions.com/etexts/id/more-utopia-221"
     owl:sameAs="http://dbpedia.org/resource/Utopia_(book)">
     <dcterms:title>Utopia</dcterms:title>
     <dcterms:creator rdf:resource="http://infomotions.com/etexts/authors/resource/thomas-more 
" />
   </rdf:Description>
</rdf:RDF>


<!-- etext #2; points to local author and remote title -->
<rdf:RDF
   xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
   xmlns:dcterms="http://purl.org/dc/terms/"

   <rdf:Description
     rdf:about="http://infomotions.com/etexts/id/more-reality-404"
     owl:sameAs="http://dbpedia.org/resource/Reality_(book)">
     <dcterms:title>Reality</dcterms:title>
     <dcterms:creator rdf:resource="http://infomotions.com/etexts/authors/resource/thomas-more 
" />
   </rdf:Description>
</rdf:RDF>
