  1. Using Google Book Classes in MashupsExcerpt from talk given at IUG 2008 in Washington, D.C Annette Bailey University Libraries Virginia Tech April 29, 2008

  2. Part 2 Google Book Classes

  3. Mashing a Service into the III Catalog Display • MAJAX mashes catalog data into other web pages • Now we’ll mash data from another service into the library catalog

  4. Google Book Search Book Viewability API Programmatic client-side access to small set of Google Book Search information Provides thumbnails of book covers Provides link to Google’s book information, preview, or full text pages Provides information on whether Google has full text, partial preview, or no preview Indexed by ISBN#, OCLC#, LCCN# Released March 2008

  5. Goals We want to incorporate information from Google Book Search into our catalog E.g., allow users to see a preview of a book if one is available from Google Or use Google’s book covers Without JavaScript coding (even though Google’s API requires JavaScript coding as it is)

  6. Google Book Classes Demo

  7. Google Books Demo Buttons appear if Google Book Search has a partial preview of book

  8. Google Books Demo (2) Buttons appears if Google has a partial preview of book

  9. Google Book Classes • A JavaScript library and set of classes that simplify using the Google Book Search Book Viewability API • Can be used on any web page, including inside the Millennium system • Usage is much like MAJAX • Available from libx.org/gbs

  10. Using Google Book Classes(on general web server) Include the class(es) in <span> tags • Upload a copy of gbsclasses.js to your server • Include gbsclasses.js in a <script> tag in the target page <script type="text/javascript" src="http://yourserver/yourpath/gbsclasses.js"> </script> <span title=“ISBN:0596002556” class=“gbs-thumbnail”> </span>

  11. GBS Identifiers <span title=“IDENTIFIER” class=“GBS-CLASSES”></span> IDENTIFIER can refer to ISBN #, OCLC #, or LCCN# Alternate syntax: use * as IDENTIFIER

  12. Using Google Book Classes in Millennium • Include gbsclasses.js in HTML template file via <script> tag • E.g. toplogo.html • Use III fieldspec token to insert HTML that includes the Google Book Classes into the briefcit.html file

  13. briefCitPub <div> briefcit.html

  14. A Google Preview Button Inside “Publisher” box Insert 1x2 HTML table 260 Field goes in left column Link to info page – but only if Google has a partial view hide span initially Remove span if Google does not index this ISBN III will put first 020 Field here <div class="briefCitPub"><table><tr> <td style="text-align:left" width="65%"><!--{fieldspec:Vbp260}--> </td><td width="35%"><span style="display:none" title="*" class="gbs-link-to-info gbs-if-partial gbs-remove-on-failure"><!--{fieldspec:Vbi020}--><img src="http://code.google.com/apis/books/images/api-example2.png"></span></td> </tr></table></div> briefcit.html

  15. Currently Supported Google Book Classes • Thumbnails Image • gbs-thumbnail • Wrap span in a hyperlink • gbs-link-to-preview • gbs-link-to-info • gbs-link-to-thumbnail • Conditionals: only keep span if … • gbs-if-noview • gbs-if-partial-or-full • gbs-if-partial • gbs-if-full • Remove if Google does not index book • gbs-remove-on-failure • Multiple classes can be combined

  16. Google Book Classes: Summary Google Book Classes allows the use of the Google Book Viewability API in mashups Without requiring any JavaScript or AJAX knowledge Allows integration in places (such as III briefcit.html) where control of a page is limited
