Danbury, CT kicks off LibraryThing for Libraries!

Danbury's catalog, with LibraryThing for Libraries in place.
The Tag Browser in action.
We're happy to announce that the Danbury Library in Danbury, Connecticut has become the first library in the world to put LibraryThing for Libraries on its live catalog. The Danbury Library—already breaking ground with an active blog and a MySpace page—continues to innovate and experiment. And we finally have something to show people!

We hope the library world will give it a look. It's not the full and final "next generation" solution. It's not perfect. But it's something new, and--we think--quite promising. It's also available now, and only going to get better.

Underneath, the data comes from LibraryThing and its members. We've cleaned some of it up--Abby, our head librarian, and Jenny Anastasoff, a local librarian who's intern with us, have been hunting down and excluding personal or irrelevant tags.* But its strength is the strength of LibraryThing's people and their collections—200,000 members, 13 million books and 17 million tags.

An example. Let's start with Helen Fielding's Bridget Jones's Diary (http://cat.danburylibrary.org/search/i?SEARCH=0670880728), the well-known comic novel which kicked off the "chick lit" craze. The original record provides little more than the author and a single--rather useless--subject "Single women--England--Fiction."

LibraryThing adds three pieces of data:
Other editions and translations. This picks out other editions and translations of the item. In this way, a patron who discovers that the item they searched for is loaned out can discover another, available copy. The feature also creates reciprocal links between paper and audiobook editions, and between different language editions. Underneath, LibraryThing is drawing on its "works" system, a simplified version of FRBR.

Notably, we're making this feature free. You don't need to buy the other widgets and, at least for now, there's no setup cost.** There has been a lot of buzz lately about "FRBR-izing your catalog," and I've seen some very high prices quoted. OCLC's xISBN API just graduated from free to paid. We're keeping it free, and serving up features, no an XML file.

Similar books. This too is based on LibraryThing's data--the holding patterns of some 13 million books. It is not, of course, perfect. It makes mistakes--even a few howlers. But, overall, it's as good as Amazon's recommender system, and particularly well-suited to libraries. For starters, it tends to move patrons "down the long tail" or, to use a more appropriate metaphor, "into the stacks." Thus, C. S. Lewis' The Last Battle offers up two other Narnia books, but also Madeline L'Engle and Susan Cooper. Shelley's Frankenstein links to Dracula, but also to The monk by the Victorian Gothic novelist Matthew Gregory Lewis.

The Cyberpunk tag.
Tag Browser. This calls for a longer explanation. In essence, the Tag Browser allow patrons to examine Danbury's catalog using simple, common-sense terms. The terms, or tags, are drawn from LibraryThing 17 million member-added tags.

Bridget Jones's Diary
is a good place to start. Everyone knows what it is--it's chick lit. But there is no "chick lit" subject in Danbury's catalog--or in anyone else's. Even so, chick lit is "real"; patrons will want to look for it.

Knowing that a book is tagged "chick lit" isn't necessarily that helpful. But click on the tag, and it opens the Tag Browser for chick lit. The list it gives amounts to something like "The Chick Lit Reading List"--from Lauren Weisberger and Jennifer Weiner to Sophie Kinsella to Emma McLaughlin, all available at the Danbury library.

The same works for many other terms. In Danbury, the seminal cyberpunk novel Neuromancer gets no subject at all. In the Tag Browser, it shows up at the top of "Cyberpunk" (which is another good "reading list"). Even the "Science Fiction" subject falls short. Only 291 items get the subject***, which don't include Dune and Martian Chronicles (which have no subjects) or Heinlein's The Moon is a Harsh Mistress gets by with "Imaginary wars and battles--Fiction."

Tags are not always better. Subjects' authority and potential for hierarchical presentation cannot be dismissed. And, unlike some other systems, Danbury very effectively aliases common terms, mitigating some of the worst problems. Thus, "Chinese Cooking" links to a search for "Cookery--Chinese," "Ice age" maps to "Glacial epoch" and "Prozac" to "Fluoxetine." The latter picks up some items the Tag Browser tag "Prozac" does not.****
But it goes the other way too.
  • The subject "PHP (Computer program language)" misses Dreamweaver MX : PHP web development, classed soley under "Dreamweaver (Computer file)."
  • The "MySQL (Electronic resource)" subject misses the High performance MySQL—far and away the best MySQL book in the building—but under "SQL (Computer program language)."
The Usability tag.
Also with the Tag Browser, you can examine Danbury's excellent holdings for the hot and quite distinct topics "Usability" and "Information architecture." The former includes 13 books, the latter eight. Without tags, they are just part of the much larger "Web sites--Design" pile.

Or take "Mesopotamia." A Danbury subject search turns up two books of juvenile fiction, and no cross references. To get the epic of Gilgamesh, you need to known the trickier "Epic poetry, Assyro-Babylonian--Translations into English." Other key works, like "The Cultural atlas of Mesopotamia and the ancient Near East" and "Cultural atlas of Mesopotamia and the ancient Near East" fall under Iraq subjects. This isn't a bad place for them, but multiple access points are always good.

In short, by adding LibraryThing for Libraries, Danbury has opened up some valuable new ways for patrons to find books of interest to them.

How it works. Perhaps the most remarkable thing here is the relative ease with which Danbury added the feature. Danbury has an Innovative Interfaces OPAC ("WebPac"), but LibraryThing for Libraries is platform agnositic. There is no back-end integration--no one at Danbury had to call their vendor. Ultimately, it involved just a few lines of JavaScript pasted into the page footer. It works on any modern browser. It causes your tea service to fill with magical gold. Okay, not that.

Caveats.

Some things we're working on:
  • So far, it only knows ISBN books.
  • The Tag Browser is not fast enough. This can be improved, no question.
  • There are some wrinkles in the tag data, particularly in marginal cases. Some of this will go away, but not all of it.
  • There are some character problems, like the tag "C++" turning into "C."
  • In the rush to get the feature out, we forgot to give Danbury the "noscript" tag, so that users with JavaScript turned off can enjoy the enhanced content.
Improvements:
  • We wanted to start with non-interactive features. We love user tagging, but wanted to show what out existing data could do without any additional patron data. There are also sticky privacy issues there. But, of course, this is a direction we'll be moving in.
The Future. Getting one library out takes a lot of pressure off us. We've been doing a lot of custom work to show potential customers what we're going to offer. With a major test case live, we can cut back on that. We've also learned a lot more about the problems of importing library data, and are making progress there. We'll moving into "production" mode, and getting back to other libraries soon.

Thanks. Altay, John and I want to express our thanks to Kate Sheehan, Danbury's Coordinator of Library Automation, who pushed Danbury ahead of the LTFL pack through sheer enthusiasm and force of will. (Also, she checks her email constantly, which fits our work habits nicely.) Kate has an entertaining blog, Loose Cannon Librarian.

*For example, the most of "personal tags," like "to be read" and "at the beach house," have been removed. This is only about what shows up in the library catalog, obviously; nobody has been tampering with user data on LibraryThing!
**We've reserved the right to start charging a setup fee, if we get a huge rush of non-payers. So long as we can do it easily, we do not want to charge anyone. Either way, LibraryThing's underling isbn-to-isbn data will remain free and open for all non-commercial use. This is in stark contrast to OCLC's parallel xISBN service, now restriced to 500 queries a day.
***Another 147 get "Science Fiction Gsafd," surely one of the best acronyms ever developed--"Guidelines on Subject Access to Individual Works of Fiction, Drama, Etc." Unfortunately, the two subjects don't sort close together.
****Not, however Elizabeth Wurtzel's famous Prozac nation : young and depressed in America. Wurtzel's book gets two subjects, "Depressed persons -- United States -- Biography" and the wonderful "Wurtzel, Elizabeth -- Mental health." Hey, how do I get a top-level category, and another for my problems?

What about allowing LT members to mark some tags as "personal" vs "public"?

Yeah. We thought about that.

Fundamentally, we're doing a subset of all distinct tags. There's a lower limit—X users X times. It amounts to less than 40,000 distinct tags. Ploughing through that wasn't so hard.

We actually went a little past "personal." The "fiction" tag went. It's just not that useful.

I like the idea of recursive (or meta) tags like "personal" and "public". Those couldn't be rigidly categorized either (people will not all mean the same thing when they say "personal" etc), but it would allow me to distiguish between tags that deal with the lager LT work and those like location or place purchased that deal with a particular copy of a work.

The tag browser isn't working for me at all at Danbury.

I'm using Opera.

Thanks. We'll take a look. It will have to wait on the more critical issue—speed.

Thanks,

JavaScript enabled, btw.
Blogger won't let me paste in the script I get when I click a tag (not even in code tags)

A way to distinguish personal from public tags would be practical, yes.

Why not allow the items not held by Danbury Public Library to display in a list further down the page? That way if the public can create demand for them, and the collection development people at Danbury will have feedback on what to order. (Though you will have to limit it to books in print.)

That's an interesting idea—to offer as a feature anyway, particularly if you know some immediately larger body anyway.

Hmmm... I could see a list of books we don't have being interesting, but I could also see it being confusing and possibly annoying for our patrons. If those titles could be linked to a search for them in the state catalog, that would be really neat.

As for listing related books the library doesn't have, could you list them separately (or lower, as suggested) and then link to whatever the user has to fill out to request a book through interlibrary loan? Apparently, everything is available that way but many users don't know that.

Well, "Chick lit" is now indeed an official LC subject heading (created almost exactly 1 year ago)--so at least *some* catalogs should contain it by now. Though probably very few libraries will do any retrospective adding of it.

My hobby is reading. So far I have read many books in almost all kind of sections. I do not like to see this system fails to when I click it.
