    <p>I am trying to figure out how to search for a book by ISBN using the Google Books API. I need to write a program that searches for an ISBN then prints out the title, author, and edition. I tried using <code>List volumesList = books.volumes.list("");</code> but that did not allow me to search by ISBN and I did not see a way to get the information I needed(when an ISBN was placed in it had no results) . What I have right now is:</p> <pre><code> JsonFactory jsonFactory = new JacksonFactory(); final Books books = new Books(new NetHttpTransport(), jsonFactory); List volumesList = books.volumes.list("9780262140874"); volumesList.setMaxResults((long) 2); volumesList.setFilter("ebooks"); try { Volumes volumes = volumesList.execute(); for (Volume volume : volumes.getItems()) { VolumeVolumeInfo volumeInfomation = volume.getVolumeInfo(); System.out.println("Title: " + volumeInfomation.getTitle()); System.out.println("Id: " + volume.getId()); System.out.println("Authors: " + volumeInfomation.getAuthors()); System.out.println("date published: " + volumeInfomation.getPublishedDate()); System.out.println(); } } catch (Exception ex) { // TODO Auto-generated catch block System.out.println("didnt wrork "+ex.toString()); } </code></pre> <p>If anyone has any suggestions about how to make this more efficient let me know. New Code:</p> <pre><code> String titleBook=""; //////////////////////////////////////////////// try { BooksService booksService = new BooksService("UAH"); String isbn = "9780262140874"; URL url = new URL("http://www.google.com/books/feeds/volumes/?q=ISBN%3C" + isbn + "%3E"); VolumeQuery volumeQuery = new VolumeQuery(url); VolumeFeed volumeFeed = booksService.query(volumeQuery, VolumeFeed.class); VolumeEntry bookInfo=volumeFeed.getEntries().get(0); System.out.println("Title: " + bookInfo.getTitles().get(0)); System.out.println("Id: " + bookInfo.getId()); System.out.println("Authors: " + bookInfo.getAuthors()); System.out.println("Version: " + bookInfo.getVersionId()); System.out.println("Description: "+bookInfo.getDescriptions()+"\n"); titleBook= bookInfo.getTitles().get(0).toString(); titleBook=(String) titleBook.subSequence(titleBook.indexOf("="), titleBook.length()-1); }catch(Exception ex){System.out.println(ex.getMessage());} ///////////////////////////////////////////////// JsonFactory jsonFactory = new JacksonFactory(); final Books books = new Books(new NetHttpTransport(), jsonFactory); List volumesList = books.volumes.list(titleBook); try { Volumes volumes = volumesList.execute(); Volume bookInfomation= volumes.getItems().get(0); VolumeVolumeInfo volumeInfomation = bookInfomation.getVolumeInfo(); System.out.println("Title: " + volumeInfomation.getTitle()); System.out.println("Id: " + bookInfomation.getId()); System.out.println("Authors: " + volumeInfomation.getAuthors()); System.out.println("date published: " + volumeInfomation.getPublishedDate()); System.out.println(); } catch (Exception ex) { System.out.println("didnt wrork "+ex.toString()); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
