WorldCat Search API tips and tricks

There are lots of types of requests which can be made to the WorldCat Search API which aren't always obvious. One of my favorities in the "Holding Location" request type. Most developers use this type of request to find out which libraries hold a particular book.

For example -

But it also works without the filter to a specific books. So you can do requests like

which will get you public libraries in the state of Maine:

Two new visualizations for ELAG

I'm doing a presentation on visualizing library data at ELAG this week. I'm showing off some demonstrations that I built for code4lib 2011 and some new demos that I've built for ELAG. The new demonstrations for ELAG take advantage of two OCLC web services.

Two days of Linked Data at ELAG

This week I'm attending ELAG (European Library Automation Group) in Prague, Czech Republic. My first two days at the conference have really been focused on Linked Data. The first day I attended a very informative preconference on implementing RDFa for library websites. I spent 10 years working on library websites and the idea of sharing data from library website with other systems has always been near and dear to my heart. So RDFa is of great interest to me because it enables libraries to share data from their website without having to get caught up in trying to produce full RDF.

If you're also the EZproxy point person, but would like to free up some time this summer...

Then you know who you are. We all love a good routine update sometimes--especially on a gloriously sunny Friday morning. But sometimes, yes. We like to apply our grey matter to new challenges. If this is sounding like you--and you live in the US or Canada--then round up the people in your institution who need to learn more about the hosted version of EZproxy and plan to attend the upcoming Webinar next week:

code4lib North recap

Attending code4lib North last week was a lot of fun. It was terrific to see all the wonderful projects folks were working on in Ontario. I had some great conversations about web services for names and authority data, learned about new web services to play with from Canadiana and Scholar's Portal, and learn a little about R.

The two talks that stuck with me with most were

Attending Code4Lib North - Hackfest

So I'm in Hamilton, ON attending code4lib North today and tomorrow. The conference is relatively small but in some respects (less than 50 people) but perfect for having a good hackfest. I've gotten to talk to 5 people about OCLC web services. Several are interested in name authority information or sharing non authority name information between libraries, particularly libraries working on digital collections. So I pointed out VIAF and WorldCat Identities as possible sources of name information.

Using the OpenLibrary API

As one of the developers of the WorldCat Search API, I’ve been a fan of APIs and webservices for quite a while now.  And of course I’m a big fan of WorldCat.org and its links, both inbound and outbound.  So I was glad to be involved in a recent small project to supplement existing Open Library records with OCLC numbers, using their API.  Some Open Library records already had OCLC numbers, but many did not.  More OCLC numbers would make connections from Open Library records to WorldCat.org, to find physical copies, more reliable.  And for those with an OC

Updates to the WorldCat Registry APIs

There have been enhancements made recently to the WorldCat Registry to include new data elements. These new elements help support OCLC Web-Scale Management Services and mobile-specific functionality, including:
• There are changes to schemas and XML output for active and in-active records. The logical delete flag has moved to be an attribute within the Institution element.
• Better information about a library's online catalog including whether or not it is publically available or via an intranet only
