Author rating statistics

I’ve added an author sub-page for “Rating statistics.” It shows all an author’s works, together with their ratings. In addition to the average (mean), it also has rating count, median, and standard deviation. You can click on a column to sort by it, and filter out books with few ratings—useful for more popular authors.

Check out some examples: Ann Patchett, John McWhorter, David Sedaris.

Help libraries damaged by Hurricane Irene

Author Kate Messner posted yesterday about serious damage suffered by the Wells Memorial Library in Upper Jay, NY from Hurricane Irene’s floodwaters. Almost their entire childrens’ book collection was soaked beyond salvage, and they could use donations of money or books to replace the lost titles.

We’re sure there are other libraries out there in the same situation, so we want to help however we can. I’ve set up a wiki page to track needs and how to help, and I’ve contacted librarians at various libraries in the Bahamas and the U.S. reported to have suffered damage from Irene. I’ll be updating the wiki page as I get new information, but others should feel free to add to it, or to email me (jeremy@librarything.com) with updates.

I’ll be sending copies of some of my favorite childrens’ books, as well.

Flash-mob catalog Graham Greene’s library!

Flash-mob time! Help us complete the Graham Greene Legacy Library catalog by assisting with the addition of the ~2,200 remaining titles.

Greene’s library, now in the collections of Boston College, is notable for the number of books containing Greene’s annotations and marginalia.

Many thanks to LTer g026r for getting this project started!

See the wiki page for details on how to help, or discuss on the Talk thread.

Stamp your books!

Today is LibraryThing’s sixth birthday. In honor of the event, we’ve got a nifty new piece of LibraryThing swag—a good old-fashioned library stamp, so you can keep track of the books you’ve cataloged, and show off a bit too. After much deliberation and hunting, we finally found a supplier that could provide what we wanted: a decent wooden stamp with a handle that we could sell for a reasonable price.

The rubber stamp is mounted on maple wood, and we opted for the wooden handle, to give you that real library stamp feel. The impression is 1 inch by 1 inch— perfect for stamping on the first page, half-title, title page or wherever.

We’ll be selling these at $9.95 apiece, plus shipping and handling.

Order yours at: http://www.librarything.com/stamps.php

Come talk about the stamp.

Tracking popularity by date

We’ve just added a new Zeitgeist page for popularity, allowing you to track a book’s popularity over time (month, quarter, year) based on the number of times the book was added to members’ libraries over that time period. Check it out.

Arrows indicate changes in popularity over time; the number next to the arrow tells you how many ranks the book changed from the previous month/quarter/year.

For clarity, we’ve changed the home-page feature “Popular this month” to “Hot this month.” The difference is easier seen than explained, but basically “Popular this month” includes the always-popular stuff (eg., Harry Potter) and “Hot this month” includes the newly popular stuff, by comparing titles added this month to all the titles added to LibraryThing in past years. We’ll be adding a viewer for these to the Zeitgeist page soon.

Come discuss on Talk.

New tag-based recommendations algorithm

Short version. I’ve just finished up a new algorithm for calculating book recommendations based on tags. You can see them on the “Recommendations” sub-page for every work page, under a special “Tags” heading (for a limited time only!), as shown to the right. When a work doesn’t have a recommendation, it will make it. (Expect to wait 2-10 seconds.) Recommendations will be propagating through the system, and, combined with the four other recommendations algorithms we use, going into your personal recommendations over time.

Come discuss it on talk here.

Long version. Recommendation algorithms are always tricky, but doing it based on tags alone is particularly difficult. Do you consider total overlap? Overlaps by tag? How do you rate a book missing an important tag? How do you factor up meaty and meaningful tags, and downgrade meaningless, over obvious or ephemeral ones? LibraryThing has long had tag-based work-to-work recommendations, but they were of uneven quality. I haven’t been making new ones for a while now, and letting them die out of the system; all the old tag-based recommendations have been removed.

The new algorithm approaches the issue afresh, looking at all of a work’s tags, and taking into account various factors that can trip it up. It thinks about factors like tag salience on a work and generally, degree of agreement between tags and low-value tags. It also attends to similar levels of work popularity. After deciding on the basic algorithm, I toyed with various “knobs” for days, myself and with Jeremy, trying to get the best results for a set of sample and problem works. In my experience, you can’t do an algorithm like this without a sense of appropriateness, taste and proportion, and (I hope) that this is one reason LibraryThing recommendations are generally so good.

Once a tag-recommendation is generated, it takes a while for it to be incorporated into the “Combo recommendations” above. “Combo recommendations” incorporate tag recommendations to greater or lesser degrees, depending on its assessment of their quality and contribution. Your personal recommendations are based mostly on these “Combo recommendations.”

The tag recommendations are going to take a while to build for all works that need them. After that, we plan to do some sort of “Pepsi Challenge” test. We think LibraryThing recommendations are as good as any out there, and are eager to prove it.

Some examples. Tag recommendations work absolutely best on non-fiction titles about something very simple and clear cut:

Works really “about” two or more things are harder, as are books with a specific point of view, which might seem separate to some extent from the tags on it. Some examples:

  • PHP and MySQL for dummies by Janet Valade — A successful example, where most of the books deal with both PHP and MySQL, with an orientation toward “entry level” programmers (eg., the “Visual Quickstart” books)
  • Born Fundamentalist, Born Again Catholic by David B. Currie — A successful example that mostly recommends other Protestant-to-Catholic conversion stories (rather than Catholic-to-Protestant ones)
  • Goldwater by Barry Goldwater — A mixed but mostly decent result, surfacing some Goldwater-specific material, but also showing other biographies, especially from the period and involving senators. Ideally it wouldn’t have quite so many contender-bios, as I’m not sure the potential Goldwater reader is eager to dig into Edward’s bio.
  • Freakonomics by Steven D. Levitt and Stephen J. Dubner — Decent list, starting with a short-shelf of popular economics-in-life books, followed by popular introductions to economics and economics-oriented thinky-think books

Fiction, especially non-“genre” fiction, is the big problem. Literary fiction isn’t “about” what it’s about in quite the same way that non-fiction is. Creating some separation between adult and youth titles is also hard. But we’ve made significant progress.

  • Watership Down by Richard Adams — A decent list of animal-centered chapter books, with classics like Redwall and The Wind in the Willows and no The Runaway Bunny or Knuffle Bunny.
  • The Book of Three by Lloyd Alexander — A decent list of magical fantasy books, angled to youth and toward Welsh mythology.
  • The Hobbit by J. R. R. Tolkien — A good list, but obviously centered quite strongly on Tolkien. Works with significant secondary literatures (cf., Harry Potter, Narnia, etc.) tend to be dominated by guides, atlases and so forth.
  • Little Women by Louisa May Alcott — Starts out well, putting March second, but then goes off the rails somewhat after a dozen. The Mother-Daughter Book Club wins because it apparently takes place in Concord, Massachusetts and involves mothers and daughters. The Secret Life of Bees is also about mothers and daughters, coming of age, sisterhood, and was made into a movie. Meh.
  • The Book Thief by Markus Zusak — Decent list, with other books, mostly fiction, about children during the Holocaust.
  • The Shack by William P. Young — I haven’t read it, but I think have a sense of it. There are some winners here, like The Christmas List, Redeeming Love. The Year of Fog and The Deep End of The Ocean cover some of the same issues from a non-religious standpoint, and Where Is God When It Hurts covers them from a non-fiction, evangelical perspective, which might or might not be wanted. But C. S. Lewis and Paul Bunyan(!) aren’t winners, being rather different sorts of fictions. Tim LaHaye is winning almost solely on being “christian fiction,” and James Redfield for “religious fiction,” “inspirational,” etc.
  • Patient Zero by Jonathan Maberry — Zombies? We got zombies, focusing on plague-based zombie terror (no Pride and Prejudice and Zombies). Straight-up plauge titles, like The White Plague are also included. Preston’s The Demon in the Freezer probably shouldn’t be there, but it’s a great book.
  • Earth Abides by George R. Stewart — More apocalypse, this time with few zombies. The Brief History of the Dead is rather different, though I’m not sure how LibraryThing could know that. At least it doesn’t attempt to recommend other boring books, like Earth Abides.
  • Blueberry Girl by Neil Gaiman — Some good stuff. Sound lousy. The tags are dragging the recommendations all around—children, picture book, Gaiman, mothers and daughters, charles vess. Twinkle, Twinkle, Little Star is winning on “poetry,” “rhymes” and child-associated tags.
  • Love in the asylum : a novel by Lisa Carey — My wife’s book. A decent-list of insane-asylum fiction, with some memoirs.
  • Twilight by Stephenie Meyer — Largely okay, so far as I can tell, although with less secondary literature than I would have guessed.
  • Illyria by Elizabeth Hand is winning on tags like “forbidden love,” “teen romance,” “teen lit,” “romantic” and “contemporary fantasy.” I have no idea if the books are similar.

Come discuss it on talk here.

LibraryThing in embassy libraries

Did you know that the U.S. State Department helps organize and maintain libraries around the world? They are set up as Information Resource Centers at embassies and consulates, and as American Corners (partnerships between embassy Public Affairs sections and local host institutions). In Afghanistan, they’re known as Lincoln Learning Centers.

LibraryThing offers free lifetime status for these accounts, and so far more than a hundred diplomatic libraries have begun to catalog their resources using LT. Just a few of those include:

Other American Corner libraries getting their LT catalogs underway recently include a whole bunch in places like Khazakhstan, Serbia, and Fiji.

Just one of the many different uses being made of LibraryThing around the world!

Welcome Brian!

Welcome Brian Stinson (LT member tabashco), our new systems administrator: the person who keeps the servers running, plans expansions, monitors performance and protects your data.

Brian describes himself as a city kid from Witchita, KS (and writes “Before you ask, I’ve never met Dorothy, and I couldn’t grow some wheat to save my life but the Sunflower State will always be home”). He earned his BS in Computer Science from Kansas State University, where he’s soon to begin a graduate program in Political Science. Brian will be supported by the rest of the LibraryThing staff, who have become much more familiar with the systems side of LibraryThing since John informed us of his departure.

Brian likes C-Span, running, reading, college football, sledding, and listening to campus radio. His favorite authors include Ernest Hemingway, Cory Doctorow, Arthur Conan Doyle, and Mark Twain. You can follow him on Twitter at @tabashco.

New: Search your groups and connections

We’ve added a new cross-library search feature. You can now search:

This opens up all sorts of possibilities: you and your family members or friends can create a group together and easily search across the all the books in your libraries, or start a neighborhood group*. You can look for interesting books within a given group. For example, Tim enjoys searching for “Alexander the Great” in the Alexander the Great group.

Be creative, and if you do something really nifty with this feature, make sure and tell us about it!

Come discuss it on Talk. Many thanks to members of the Board for Extreme Thing Advances for help developing this feature.


* I’m already seeing Tim combining this new feature with the “what should you borrow?” recommendations so that he can plunder my bookshelves!
