Mash-Up the OPAC

ILS user groups can be one of the greatest sources of tips, tricks and inspiration for tech-oriented library staff. There was a recent discussion on the Innovative User’s Group that has led to an interesting way to embed various media into OPAC search results.

Each of these work in Innovative’s Millennium OPAC. I have not had a chance to check whether this will work in other systems, but would greatly enjoy hearing whether or not it works for others.

The key to this is the MARC 970 field, using the subfield |t, which is used for Table of Contents display information. It was observed that the contents of the field were passed along to the browser, and that html code could be passed to the bibliographic display.

It works well, and is a perfect example of a “hack”, utilizing existing functionality in new and creative ways. To date, there are six ways to extend the OPAC.

To try out these examples, simply copy the html code, starting with the |t, and paste it into a 970 field in a bibliographic record. Each of the examples should work as is; some information about how to modify the code, as well as a screenshot of the example is provided.

Displaying an Image:
This is fairly straightforward insertion of an image stored on Flickr. Change the URLs to whatever you need, adjust the pixel height and width, and this will serve you well.

Embedding a Search Form:
This code embeds a search form for OpenLibrary, including a selector check box and link to an advanced search page. Search forms can be tricky, and it can be very challenging to get even basic search functionality for some services.

Embedding a Video:
This example embeds a YouTube video, specifically the preview for the film “A Streetcar Named Desire”. Previews of videos available in the library, library instructional videos, and author interviews are examples of the types of embedded video that add can value to your OPAC.

The embedding information comes from the “Embed” information from the YouTube result page. You can also simply replace the URL information in the code below:

Streaming Audio:
This example uses a third-party service called Odeo to stream the MP3 audio of Martin Luther King Jr’s “I Have a Dream” speech. The audio file lives on the Internet Archive.

Journal Table of Contents
This example utilizes two separate third-party services. First, the ticTOCs Journal Tables of Contents service is used to locate an RSS feed for a table of contents, in this case “Educational Research“.

After this, the feed URL is entered into the Feed2js service, which generates the code. To display any RSS feed, simply use the Feed2js service with a feed’s URL.
