OutlinePart I Perceptions of Library & OPAC How Bad Is OPAC? What is a Next Generation Catalog? Demo on a commercial NGC

Part II Demo on HKUST Scriblio What Do We Think? Other Desirable Features Q & A


For many years ……The Library Catalog:

Is the primary means of locating library’s collections.

Display the holdings of the library.

Over the last decades, the catalog’s functions have evolved a lot. Now, catalogs also act as an access mechanism to resources beyond the library.


Perceptions of Library & OPACIn 2005, OCLC conducted a study and found:

89% of college students uses search engine. Only 1 % use library website to begin information search.

Use the library less and more time spent on Internet.

Search engines fit users’ lifestyle better than physical or online libraries.

90% of study respondents are with search engines. Search satisfaction has a strong correlation with the quality & quantity of information returned in search process.

The OPAC SucksRecorded by: the anAACRonisms

the OPAC sucks, that's all i gotta say

i'm getting bad results. don't act like it's my fault

the OPAC sucks, a sad calamitylike it's stuck in 8 million b.c.

the OPAC sucks so bad that it's a crime what does it want from me?i'm stumbling blindly

the OPAC sucks, people are confusedit runs amok, committing its abuse

the OPAC sucks, that's all i gotta say ... (Lyrics and music: Brian Smith)

you’re outta luck if you can’t spell “Hemingway”

the title that I seek is buried very deep

the law is broken “save the reader’s time”

years and years and years ago, computers replaced cards how come find what I want is still so goddamn hard?

So What’re the Problems? Made for librarians, not patrons.

Best for “known-item” searching , not topic searching.

No relevance ranking. Most catalog search results are simply ranked last-in/first-out.

No cutting edge features (e.g. Blog, Wikis & RSS feeds)

Too much text and Boolean-based More…
