Hi,

I updated the OPDS for openlibrary.org edition records to include the =
new OPDS 1.1 indirect acquisition elements.

Is there a way to indicate that a book is currently checked out and =
currently unavailable? Right now I remove the acquisition links if the =
book is checked out, but it would be nice to indicate to users that the =
book would be available at a later date.

Example:
If this book isn't checked out of Open Library's lending library:
=
http://openlibrary.org/books/OL24620870M/The_Elements_of_Content_Strategy

Then its OPDS entry will contain indirect acquisition links:
http://openlibrary.org/books/OL24620870M.opds

Which looks like:
  <link rel=3D"http://opds-spec.org/acquisition/borrow" type=3D"text/html"=
 =
href=3D"http://openlibrary.org/books/OL24620870M/The_Elements_of_Content_S=
trategy/borrow">
    <opds:indirectAcquisition type=3D"application/vnd.adobe.adept+xml">
      <opds:indirectAcquisition type=3D"application/epub+zip"/>
      <opds:indirectAcquisition type=3D"application/pdf"/>
    </opds:indirectAcquisition>
  </link>
