WorldCat (April) Fools

Written by:

This is the first of a few new blog posts. It’s April 1, April Fools Day, but there is, alas, no foolin’ around here. It’s just bad news, start to finish, with the WorldCat subject entity links that have been in the free ShipIndex database since 2009. Read on, to learn more.

When ShipIndex switched from a personal project to a real company, back in 2009, I put all of the citations that had been in the “project” database, into the free database. Anything new was going to go in to the subscription database. I had been in contact with researchers at OCLC, the very large library cooperative that ostensibly helps libraries manage their resources, and shares those holdings, via their publicly available database called WorldCat. I worked with several remarkable people there, who through the years generated a list of all of the “identities” for ships in WorldCat.

This meant we could find books or manuscripts that were by or about ships. So, a book about a ship is easy enough to imagine – the book The Royal Yacht Britannia: The Official History is clearly about that vessel. Having a specific subject heading about that specific yacht makes it easier to differentiate between vessels with the same name. It also created links to books by ships, which often meant logbooks our individually-kept personal journals by people who were on board a vessel. It was a great way of uncovering a lot of useful content about ships that wouldn’t be found otherwise.

But the folks at OCLC said this content needed to be in the free database, not in the then-nascent subscription database. That was fine with me; it was worth including that content and keeping it freely available. The file has been updated occasionally over the past few years, and has always been in the completely free database.

Two or three weeks ago, I was doing some searching, and looked at WorldCat records. I saw notices indicating that the OCLC Identities project, on which these links were based, was going away. This past week, all the links to WorldCat failed. OCLC has ended this project, and with it, links to lots of content that used to be in the database. They’ve also removed linking by Library of Congress Control Number. You’re just searching by phrase now – this seems like the total antithesis of the ideals behind Linked Data.

I have figured out a way to make these links mostly work. The links are now searching by subject headings, rather than by control numbers or identities. As a result, in many cases, they won’t work effectively. In the old file, there was a search to an identity for a ship named “104”, and it specifically went to the entry for a specific ship with that name. Now, the search is for any entry that has both terms “104” and “ship” in a subject heading, so instead of one or two specific results, you get 38 results. Some refer to ‘cruise 104’ of a different vessel. It’s really too bad. Searches for ships like “Mary” are going to terrible, because they’ll include ships named “Mary Rose”, “Mary Ellen”, “Mary & Frank”, “Mary Smith”, and any other ship that has ‘mary’ as just part of its name – instead of going directly to the ship you’re researching. A search for a single, common word ship name, like “Eagle” or “Union” or “James” or “Monitor” or “Wasp” is going to return any record that has that word anywhere in the list of subject headings, even if the term doesn’t have anything to do with a ship name. Connections we’ve made, between specific vessels represented in WorldCat and other citations for those specific vessels, are probably no longer relevant.

OCLC did some work in creating Virtual International Authority File (VIAF) records for some ships, as well. Again, this was great in differentiating between ships with different names. But as far as I can tell, that is also all wiped out.

I’m disappointed and frustrated by this change, as I am with most of what OCLC has done to WorldCat over the past few years.

I’ll leave with this image I collected from WorldCat a few weeks ago, telling me that a copy of a book I wanted was at the State Library of South Australia, but that library is further than the distance to the moon:

My frustration with WorldCat – and OCLC – is ancient news, but it does just keep getting worse. This is really unfortunate. This is NOT a good April Fools joke.

Using WorldCat Records in ShipIndex.org: Part 1, Finding Books Mentioned in the Database, and Finding Books About Ships

I’ve been meaning to write a blog post about using WorldCat through ShipIndex.org. I finally started, but as usual, my blog post has grown to be much too long for just a single post. So I’ll split this into two posts: one on finding monographs (ie, books) through WorldCat, and one on finding manuscript works through WorldCat. WorldCat does many different useful things in the ShipIndex.org database.

First, what is WorldCat, and what kind of records do you find there? WorldCat is a massive database that shows what books and magazines are owned by libraries in the US and around the world. WorldCat is created and managed by OCLC, an Ohio-based library services company. The first great application of WorldCat in ShipIndex.org is in helping you locate a book that mentions a ship of interest to you. I believe that knowing that a mention of a ship exists gets you at least 75% of the way to finding that citation. If you didn’t know the citation existed, then it wouldn’t count at all. But if you know it exists, then there are lots of ways of getting your hands on it, and seeing what it says. The easiest way is to see if a library near you owns the book, and here’s where WorldCat is a huge help.

If you click on “Find in a library near you” on any monograph (book) or serial (magazine) citation in ShipIndex.org, WorldCat will try to figure out where you are, and then locate the library nearest to you. You can always put in a ZIP code or a city name, too, to customize your search.

For example, imagine you’re searching for information about the ship “Punnet”. The premium ShipIndex.org database tells you that it’s mentioned in H. T. Lenton’s massive volume British & Empire Warships of the Second World War, on two different pages. You don’t own that book, so where can you find a copy?

WorldCat-1

Click on “Find in a library near you”, as shown here, and it’ll take you to this page in WorldCat that shows you more about the book, and most importantly, where the nearest copy is. In my case, WorldCat reports that the nearest library with this book is less than a mile away! (I’m lucky that way.)

WorldCat-2

Other libraries also have it, and maybe one near where I’ll be going has a copy. For instance, if I’m headed to Chicago on some upcoming trip, I could put in a Chicago ZIP Code (or just type “Chicago, Illinois”), and find out what libraries in the city own a copy. (Chicago Public Library and University of Chicago Library both own it, I find.)

If there’s no library near you with a copy, remember that you can almost certainly request that a copy be sent to you through your local public library, via “inter-library loan” (ILL). ILL is sometimes free, and sometimes costs something — but remember what a great thing the library did for you, and be sure to provide a bit of financial support to them for helping you obtain this volume!

 As a somewhat advanced aside, it’s definitely worth looking through multiple records in WorldCat. For technical reasons, not all holdings records (ie, “my library owns this book!” messages) are attached to a single bibliographic description of a book. This is especially true for American versus non-American holdings: if you only see European libraries that own a book, and you’re in the US, be sure to see if there are other records that display American libraries’ holdings, and vice versa.

There’s more to WorldCat’s content, however. One of the great collections of resources in the free part of the ShipIndex.org database is the set of about 40,000 authority records from the WorldCat database, but there can be some challenges in using the results you find there. I thought it would be useful to describe how best to use the results you find here.

WorldCat’s holdings identifies books that are about a specific ship, along with manuscript information about specific ships. In the first case, it’s important to recognize the difference between WorldCat results and other results in the ShipIndex.org database. Any given book will be assigned subject headings by professional librarians. Most books only get a handful of subject headings (rarely more than, say, six), so a book needs to be substantially about a specific ship, if it’s going to have a subject heading for that ship. Lincoln Paine’s 2000 book, Warships of the World to 1900, has the following subject headings: Warships — History, and Warships. That’s it. There’s no mention in the subject heading of the specific vessels mentioned in that book. That’s what ShipIndex.org does: it tells you which specific ships are mentioned in this book. But when you want to find the book, the “Find in a library near you” tool helps you do just that.

If a book is about a specific ship, however, there will be a subject heading for the book, which will also appear in WorldCat. For example, Cathryn Prince’s recent book, Death in the Baltic: The World War II Sinking of the Wilhelm Gustloff, has as its primary subject heading Wilhelm Gustloff (Ship). Through ShipIndex.org, you know that an entire book about the Wilhelm Gustloff exists, and you can track it down through whatever channels work best for you.

Wilhelm Gustloff

Several years ago, folks at OCLC were kind enough to generate a list of subject headings that cited ships. We agreed that these citations would be added to the free collection, not the subscription database. The result is that ShipIndex.org helps you quickly and easily find books that are by or about the ships in question, which is super-great.

Wait a minute – what was that about books by ships?

That’s the other part of the collection of records from WorldCat, and the subject of part 2 of this blog post.

 

New functionality added: “Find in a library” links

Yesterday and today, we’ve added “Find in a library” links to every single resource currently in the database. This is useful for tracking down the specific title that mentions your vessel. Say, for instance, you’ve done a search for the ship Smart. You find two mentions of the vessel, in two books about Maine ships. When you click on either title — A Maritime History of Bath, Maine, or Fairburn’s Merchant Sail — you’ll see the linked words “Find in a library”. When you click that link, it’ll take you to WorldCat, a global directory of libraries’ holdings.

WorldCat will show its record for that book, and will even do its best to find the copy nearest  you. You can put in a location to be even more exact, if you like. (The location can be a ZIP code, a postal code, a city, or a country.)

In nearly every case for items in this database, you’re only looking for a small part of the book or resource in question. You can almost certainly use the library nearest you, even if you don’t have a borrower’s card from that library. All you really need is the book and a photocopier, or the book and a pen and paper, and you’ll get the data that’s available there.

This is a big step forward in being able to track down the resources, once you’ve identified that they mention the vessel you’re seeking.

We’ll be adding more ways to locate specific resources over the next few weeks, so keep an eye on the resources pages. If you have thoughts about features you’d like us to add, or more ways to find the specific resources, please let us know.

Enjoy!
