I developed an application for the Harvard Library that displays technology available for loan. I originally developed the app for the Cabot Science Library, but provided enough flexibility that it could be expanded to include other libraries on campus.
The app displays a responsive grid of images and titles of items in the collection. The grid can be sorted by item category, library, or loan period. Clicking on an image on the grid takes the user to additional information about that item, including a link to the Harvard Library catalog (HOLLIS) to determine if the item is available or checked out.
Data about each item is provided by the Drupal CMS, which is also used by librarians to add and edit items. These users already use the same instance of Drupal to maintain library web sites, and so it made sense to use the Drupal user interface for content authoring; that way library staff can update the app without needing to know the details of how it works.
