Mashing a service into the iii catalog display
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


Google book search book viewability api
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


Goals
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)



Google books demo
Google Books Demo

Buttons appear if Google Book Search has a partial preview of book


Google books demo 2
Google Books Demo (2)

Buttons appears if Google has a partial preview of book


Google book classes
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

Using Google Book Classes(on general web server)

Include the class(es) in <span> tags

<script type="text/javascript"

src="http://yourserver/yourpath/gbsclasses.js">

</script>

<span title=“ISBN:0596002556” class=“gbs-thumbnail”>

</span>
