Problem
Sometimes you expect to see a certain book in your circulation manager's OPDS feed, but it just doesn't show up. There are a number of things that might have gone wrong.
Solution
Step 1 The simplest thing to do is to run the bin/repair/where_are_my_books script. This will force-refresh various parts of the system that are normally refreshed on a slow timescale -- once an hour or once a day. On a new system, where none of your books are showing up in feeds, where_are_my_books will also diagnose systemic problems that might indicate a problem with your importer.
Step 2 If where_are_my_books doesn't fix your problem, you need to pick a specific book and see what's wrong with it. The best entry point is the bin/informational/explain script. You explain a book by passing in its primary identifier:
$ bin/informational/explain --identifier-type="Axis 360 ID" 0010163843 $ bin/informational/explain --identifier-type="Overdrive ID" 019f21e3-9de9-4c40-95a4-dfabf55e7801 $ bin/informational/explain --identifier-type="URI" http://www.gutenberg.org/ebooks/289 Or you can run it with the internal database ID of the Identifier: $ bin/informational/explain --identifier-type="Database ID" 101
Or you can run it with the internal database ID of the Identifier:
$ bin/informational/explain --identifier-type="Database ID" 101
$ bin/informational/explain --identifier-type="Database ID" 101
The output looks like this:
