OCLC services will NOT be available on 5 June 2016 9:00 am to 12:00 midnight (SGP Time) for technology upgrades

The below message is from OCLC:

OCLC services will be unavailable from 9:00 pm 4 June to noon 5 June (EDT US) approx. equivalent to SGP Time 9:00 am (5 June) to 12:00 midnight (6 June) for technology upgrades

As we have communicated in previous messages, OCLC is undertaking a significant investment in our technological infrastructure. We are evolving our data center strategy, upgrading equipment and infrastructure, and standardizing processes globally to increase service responsiveness. These investments will advance our service delivery for years to come so that together we can better meet library users’ increasing expectations.

This year-long effort is well underway. Much of the work is occurring behind the scenes. Some of these transitions require scheduled downtime for services.

As part of this initiative, all OCLC services will be unavailable from 9:00 pm Saturday, 4 June 2016, to 12:00 pm (noon) Sunday, 5 June 2016, Eastern Daylight Time (EDT) US (UTC -4) while we conduct data storage migrations.

While we scheduled this maintenance event to occur during a slower time for many of our member libraries, we understand that this event still impacts many. We apologize in advance for any disruption to you and your users.

As always, system activities and schedules can be viewed on our System Alerts page on the OCLC website. We will communicate through the System Alerts page if there are any changes or delays in completing this scheduled work, and we will also use this page to let you know when this work has been completed.

We are committed to the ongoing enhancement of our systems, infrastructure and processes, and we will continue to advance our delivery to you. Thank you for your continued support.

Cataloguing is the organisation of information

If you ask librarians ‘What is cataloguing?’, very often you will get a reply like ‘Cataloguing is the organisation of information’.

The statement is true. In fact, we should say ‘Cataloguing is the organisation of information resources’. We are organising the resources (the things, the books, the physical objects) by their common characteristics.

We organise by the subject matters of the resources.

We organise by the creators, or the authors of the resources etc.


Rimmf (RDA in Many Metadata Formats) is a free tool developed by The Marc of Quality (

It is:

  • a visualization tool for catalogers, to help them to get used to thinking RDA, instead of thinking AACR/MARC.
  • a cataloging training tool, to help educators teach RDA thinking

RIMMF is not a cataloging tool, because you cannot save records that you can actually use in your ILS, but it does let you apply RDA thinking and practice making, cloning, and copying WEMI and other RDA entity records, so that you can get a solid idea of how much the RDA way of thinking will change the way we do cataloging, hopefully for the better.

To learn about and download RIMMF, visit the RIMMF wiki: it and you will have a better idea what RDA records supposed to be.

Here is a YouTube video from Library of Congress.

Cataloging educator Deborah Fritz and library software developer Richard Fritz founded “The MARC of Quality” in 1992 to provide training, software, and database services to libraries worldwide. Deborah demonstrated RIMMF (RDA in Many Metadata Formats), a template system that helps catalogers visualize RDA thinking to create records using the new cataloging instructions “RDA: Resource Description and Access.” There is a demonstration mid-way through the presentation that viewers may pause and view on their own devices here.

From Keywords Search to Entities Search

Further to my last post of Google Launched New Search Algorithm “Hummingbird”, here is another article from the giving more details of the new move of Google Search Engine: Future SEO: Understanding Entity Search.

In this article, Paul Bruemmer explains the concepts of “Entities” and how Google relies on entities rather than keywords in its search algorithm. The article also provides a good reference list of Semantic Web and Linked Data technology at the end.

The message here is clear: we should no longer say that Google search is merely a keywords matching search, and our library catalogues do more than that.

Hope you enjoy reading the article.

Metadata Schema for Video Games

Some libraries now include video games in their collections. This is a paper published in

Developing a video game metadata schema for the Seattle Interactive Media Museum


As interest in video games increases, so does the need for intelligent access to them.However, traditional organizational systems and standards fall short. To fill this gap, we are collaborating with the Seattle Interactive Media Museum to develop a formal metadata schema for video games. In the paper, we describe how the schema was established from a user-centered design approach and introduce the core elements from our schema. We also discuss the challenges we encountered as we were conducting a domain analysis and cataloging real-world examples of video games. Inconsistent, vague, and subjective sources of information for title, genre, release date, feature, region, language, developer and publisher information confirm the importance of developing a standardized description model for video games.

Google Launched New Search Algorithm “Hummingbird”

What type of “new” search activity does Hummingbird help?

Conversational search” is one of the biggest examples Google gave. People, when speaking searches, may find it more useful to have a conversation.

“What’s the closest place to buy the iPhone 5s to my home?” A traditional search engine might focus on finding matches for words — finding a page that says “buy” and “iPhone 5s,” for example.

Hummingbird should better focus on the meaning behind the words. It may better understand the actual location of your home, if you’ve shared that with Google. It might understand that “place” means you want a brick-and-mortar store. It might get that “iPhone 5s” is a particular type of electronic device carried by certain stores. Knowing all these meanings may help Google go beyond just finding pages with matching words.

In particular, Google said that Hummingbird is paying more attention to each word in a query, ensuring that the whole query — the whole sentence or conversation or meaning — is taken into account, rather than particular words. The goal is that pages matching the meaning do better, rather than pages matching just a few words.

I thought Google did this conversational search stuff already!

It does (see Google’s Impressive “Conversational Search” Goes Live On Chrome), but it had only been doing it really within its Knowledge Graph answers. Hummingbird is designed to apply the meaning technology to billions of pages from across the web, in addition to Knowledge Graph facts, which may bring back better results.”

So, we should not say Google Search is just exact words search. In fact, now is more than that. Much closer to semantic search.

Deciphering the Semantic Web


Deciphering the Semantic Web

What is the Semantic Web? Technology Voice recently interviewed some leading Semantic Web researchers with both academic and industrial experience to find out what it is, why it is needed, and what are the exciting applications of semantic technologies.

The results of these interviews are captured in our exclusive 44-minute video, “Deciphering the Semantic Web“.”

Public View of RDA Records

There are new fields created in MARC21 to cater for RDA (for example: 264, 336, 337, 338). Libraries have to make a decision on how and what to show the information of these fields in the public catalogue. Kent State University Libraries has decided to show each 264 fields in one line with specified labels; and omit the 337 field and show the 336 and 338 together in one line with the label “format”

Here is one example.
