Scaling de-duplication in WorldCat: Balancing AI innovation with cataloging care

We first shared our efforts for leveraging machine learning to improve de-duplication in WorldCat in this 2023 blog post on “Machine Learning and WorldCat.”

De-duplication has always been essential to maintaining the quality of WorldCat by enhancing cataloging efficiency and streamlining quality. But with bibliographic data pouring in faster than ever, we need to address the challenge of keeping records accurate, connected, and accessible at speed. AI-powered de-duplication offers an innovative way to scale this work quickly and efficiently, but its success depends on human expertise. At OCLC, we’ve invested resources into a hybrid approach, leveraging AI to process vast amounts of data while ensuring catalogers and OCLC experts remain at the center of decision-making.

From data to action: Leveraging insights to make more informed collection decisions

“How many books are there on Islamic law?”

This was the deceptively simple question posed by a colleague while brainstorming the potential scope of a digitization project on Islamic legal history. For non-librarians, it might seem like something one could just “look up.” But as you and I know, that kind of analysis only begins with a simple question and branches out into many more complex issues of data analysis, accounting for duplicate titles, different editions, and multiple languages, etc.

But I decided to give it a go and survey a selected number of libraries in North America using the tool Choreo Insights. I published the in-depth results of my findings in another post on the Islamic Law Blog, but today wanted to talk more about the process.

OCLC’s role in advancing library linked data

There are times when a single organization’s decision to embrace a particular technology will have an outsized influence on everyone else in that sector. For example, with the release of “Toy Story” in 1995—the first feature-length film entirely created with CGI—Pixar set a new standard for animated movies. While CGI had been used before, the success of Pixar’s approach encouraged other studios to adopt the technology more quickly and fully.

We are at a moment like this today. The shifting of operational workflows to incorporate linked data will transform how libraries create, manage, and improve WorldCat, the largest source of library metadata in the world. OCLC’s strategy to champion this change, along with the support of its thousands of members, represents a significant event for the library profession worldwide.

How linked data can help libraries make more of an impact online

In a recent post, I introduced the topic of linked data for libraries and OCLC’s plans for moving forward. Today, let’s dig into the details on how linked data amplifies the knowledge in library collections and the tools we can use to make it happen.

This shift toward linked data isn’t just a technology upgrade, but a long-term strategy for enhancing the findability and accessibility of the important materials that libraries curate and manage. It’s a technical challenge, yes. But I also believe it’s a chance to better promote our values.

Connecting with libraries, reaffirming our mission

Earlier this month, Columbus wasn’t just the capital of Ohio, but a center of knowledge and literacy as it welcomed public library professionals to the Public Library Association 2024 Conference. Hosting this conference was a testament to Columbus’s status as a hub of technical and educational engagement, and to the important role that public library professionals play in our country’s intellectual and civic lives. That focus continued with National Library Week 2024. This year’s theme, “Ready, Set, Library!” was such a great way to think about libraries—not only as places where learning, growth, and education happen, but as active, engaged partners in so many ways.

OCLC staff were very much involved at PLA and during National Library week. So now that things have calmed down a bit, I want to take a moment to reflect on what libraries mean to me.

Engage faculty and students with digital collections

There are almost as many reasons for digitizing library collections as there are collections themselves. Public libraries may do so to curate and promote unique local history or culture. Museums, of course, want to make their treasures available for study and enjoyment to people who can’t visit the physical building. And while academic libraries have just as many, varied reasons for beginning a specific digitization project, there’s often a longer-term goal in mind: to promote study and learning around the collection.

An introduction to library linked data

We recently announced a comprehensive strategy to bring linked data into mainstream library cataloging workflows. It’s a long-term approach, recognizing that most libraries will move to linked data slowly and incrementally—and we’re committed to providing tools and resources to support the transition for everyone.

Working closely with libraries around the world, we know that staff at some libraries are already educating themselves on the topic, piloting linked data services, and taking part in ongoing research. But we also know that many others have a lot of questions. In addition to technical issues, librarians are also wondering how linked data will impact and affect the work they are currently doing. To help, OCLC is rolling out linked data infrastructure and services that meet libraries where they are today and provide meaningful improvement to challenges facing libraries.

Lessons on building community while building the new OCLC Community Center

Next blog banner for post on OCLC community center update. Six icons representing features of the community center are shown.

If you participate in the OCLC Community Center, you’ll know it’s recently had a major upgrade. We’re happy with the results and excited about the possibilities ahead. But getting to this point wasn’t easy. It’s been a long road. And like many large-scale tech projects, the takeaways go well beyond the new software.

Every twist and turn offered lessons about how to better create valuable content and meaningful connections with our users. The truth is, we learned a lot more than ever expected about building community. And we’re hoping our experience can provide insights that inspire and inform your work to connect and engage with the communities you serve.

Expand horizons with diversity and inclusion

I shared earlier this month that we were once again ranked first in Computerworld’s “Best Places to Work in IT.” Among midsize companies globally, we’re in the top ten for IT growth and in the top position for benefits and diversity strategy programs. By focusing on technology, staff, and diversity, we can deliver better results for OCLC member libraries.

In my last post, I shared how our focus on technology and staff enables us to continuously innovate and more than occasionally transform how libraries work and serve their users. Now I’d like to talk a bit more about how nurturing an inclusive and diverse culture takes us even further.
