DeweyBrowser
The DeweyBrowser is a research prototype that supports searching and browsing collections of resources organized by Dewey
The prototype was developed to make the most of DDC numbers assigned to library materials and to explore the use of AJAX (Asynchronous JavaScript and XML)
OCLC Research OCLC Online Computer Library Center
DeweyBrowser
The interface presents search results at three levels, i.e., the three main summaries of Dewey
To use the prototype, a user navigates up and down the Dewey hierarchy by clicking on a category or enters a search term
The categories are color-coded to indicate where matching records occur
red, orange, and yellow (warm colors) — many records
green and blue (cool colors) — fewer records
white — no matching records

Summaries can be displayed in English, French, German, Spanish, or Swedish
Search and browse results can also be limited to resources written in a particular language

DeweyBrowser
The DeweyBrowser has been deployed over three collections of resources:
ebooks - 210,000+ electronic books
wcat – 2.2 million of the most widely held WorldCat records
abr14 – selected data from the Abridged Edition 14 of DDC
WorldCat and ebooks collections are linked to the Find in a Library Web service
OCLC Research OCLC Online Computer Library Center
Dewey Browser
The Abridged 14 collection includes a collaborative editing feature that enables authorized users to suggest index terms for a DDC class (Suggested terms)
Suggested terms will be delivered to interested users via RSS

DeweyBrowser & AJAX
AJAX is an approach to programming web interfaces that allows user interaction with a web page without refreshing the whole screen
Using AJAX speeds up the interface by only requesting parts of a page
Refreshing only the part of the screen that changes tends to encourage exploration, behavior that is central to how the DeweyBrowser was designed to be used
The DeweyBrowser is an example of an entire application built using AJAX

Curiouser
Curiouser is an approach to making the best use of data about items in WorldCat and a user interface for exploring and selecting works and items
The prototype interface employs the OCLC FRBR work-set algorithm exploits structured data in bibliographic, authority, and
holdings records, integrates techniques from FictionFinder for display and
navigation of records in a FRBR context, explores Web services and other data sources to enhance the
utility of Open WorldCat

OCLC FRBR Work-Set Algorithm
A work set is a group of bibliographic records with the same Author/Title key
A key is generated for each bibliographic record
Variant forms of names and titles are converted to established forms based on the OCLC authority file
Keys are sorted and compared to form work sets
