KohaCon 2011

By Noufal

Anand and I attended the Koha Conference in Thane, Mumbai earlier in November and spoke about Open Library. The conference took place from Oct 31 till 2 November. There was a hackfest following the event from 4th to 6th.

We missed the first day and presented our talk on the second day of the event. The first day had a number of interesting talks mainly about libraries shifting to Koha and about deployment issues. We spent our free time speaking to Robin Sheat, Dobrica Pavlinu i and Ian Walls among others about ways to tie up the Open Library data along with Koha installations. While the audience was somewhat small, it was truly international. There were folks from Kenya, Nigeria, France, the States, New Zealand, Australia, Croatia and of course various parts of India. We also met Savitra who apart from being a Koha developer, runs a Bangalore based company called OSS labs that provides hosted Koha instances for libraries.

We presented on the last day. Our slides are available at http://internetarchive.github.com/kohacon2011-presentation/. It was an introduction to Open Library, the data we have and some discussions on the API. There were a few questions mainly about copyright issues and about the classification system we use on the website. The conference was attended by many librarians and two of them (The Institute of Management Studies Library at VPM Thane and the University of Zagreb Faculty of Humanities and Social Sciences Library, Croatia) have applied to join the Open Library Lending Library program.

After the presentations, November 3rd was a day off and we spent it wandering around the older parts of Mumbai. On November 4th, we went back and spent the morning brainstorming about ideas to implement. We came up with a few

The first is a simple database update that presents OL as a search option when a book is not found while searching in a Koha installation. It’s been done and signed off.

The second was a simple Javascript change that fetches covers and borrow information from Open Library and then presents it when searches are done on Koha. This has been implemented as well.

The third is the most involved part and we have started work on an API to upload covers to OL which can be used by any external program. We have also started work on an API for Koha to search our records to see if the book being added is already in our database (in which case, it can auto complete the details for them). The search will also return the cover if it exists. On our end, if the koha side agrees, we can populate our database with the catalogue record being searched for and if a cover is uploaded, we can get a copy of that as well. This means that if a Koha instance in one library has uploaded a cover, other libraries will be able to use it. On the Koha side, Robin has a private branch that contains the work in progress. Details are in the bugzilla entry.

We’re following up on the bugs and the lending library requests to join. On the overall, it was a wonderful event and one that benefited Open Library as well as Koha.

Snowflakes

By George Oates

I just stumbled on a beautiful, recently-scanned book about snowflakes, published in 1863. Apart from its gorgeous illustrations, the author’s opinions about snowflakes are also fascinating.

By the way, the other day we added a little link on any Internet Archive pages that are echoed in Open Library that sends you straight to our open, editable record for that item, so, if you’re surfing around the Archive’s Texts collection and you find a book we have a record for, you can just jump across and – if you’re so inclined – help to flesh out the information we have about it.

The even more interesting thing about this is that Hank (who coded up the stuff from the Archive side) simply has to construct a URL at Open Library containing an Internet Archive item ID, like this:

http://openlibrary.org/ia/snowflakeschapte00warr

This is a small step towards something much more awesome. (We should note that what makes this work is that we’re just “across the hall” from Hank, so we were able to do a little testing and tweaking to make sure the link was offered only when we could count on there being an Open Library page for the book, but still!) The hope is that external sites can send along, say, and ISBN, or an LCCN identifier to poke into Open Library and see if we have a record.

The next logical step is to make a web service that can handle this sort of inquiry. We don’t have that just yet, and current performance is slow, but, it’s really exciting and something we aim to strengthen. It would mean that people could query Open Library for records even if they don’t know an Open Library identifier (but have an alternative identifier that we know about). The current list of identifiers we can record are: Dewey, LC, ISBN 10, ISBN 13, LCCN, IA & OCLC.

Another wish is to open up the sorts of identifiers that you might attach to an Open Library catalog record, for example, from our friends over at LibraryThing, or GoodReads, or any number of awesome book sites out there. Things get interesting if you consider the possibility that there may never be a canonical identifier for a book, but rather that there will always be many different ones. That consideration allows you to open up a pipe to any identifiers we can find, which makes for many more potential connections.

Snowflakes, indeed.

New Right-to-Left Capability in Book Reader

By mary murrell

Nearly 11,000 Yiddish books (half of all Yiddish books ever published) recently went online through the Internet Archive in cooperation with the National Yiddish Book Center‘s Steven Spielberg Digital Yiddish Library. As part of this project, we’ve upgraded the Internet Archive Book Reader to support the right-to-left page progression of Yiddish books. Here is an example.

We’ll be working to adjust the metadata of our books from other right-to-left languages, such as Arabic, Hebrew, Urdu, and others, so that they will work in the book reader, too.

Although the book reader is now available to view only through archive.org, we are working to bring the book reader to openlibrary.org as well. Stay tuned!

OLPC Bookreader Demonstration

By webchick

Open Library recently launched a web demonstration designed to illustrate how Internet Archive book collections can be viewed on the OLPC XO Laptop.

We invite you to take a look!

It is still in the early stages, and is built on open source software using an embeddable AJAX reader and a software component known as Carousel which scrolls through the collection of books on the right.

We would like to have feedback on how to improve the user experience of this demonstration and its underlying components for users of the OLPC XO and Open Library.

There are a few known bugs in the collections (i.e., Carousel) navigation:

  • A user cannot quickly scroll to the top and bottom of the collection
  • A user cannot view multiple collections, and sub-collections, or filter book selections on a variable such as author or subject
  • More books should be revealed in the collections carousel on screen rotate
  • Book titles should be truncated so they do not break into two lines (this interferes with the viewable area of the carousel)

At this time, it is not fully functional in tablet mode on the XO yet – this has dependencies on the GnuBook reader (the embeddable reader that enables scrolling through the individual book pages). We need it to:

  • Respond to the arrow keys when in tablet mode (book and collection navigation)
  • The book should zoom to fit width in the book viewable area
  • A two-page view on default is preferable to a single page view

We created an OLPC bundle for browsing books offline on the XO. It currently contains 5 books, and uses low resolution images to improve download speed:

Bundle: http://openlibrary.org/static/olpc_bundle/openlibrary.xol

We encourage anyone interested in these two projects to help betatest the software components. The primary focus is on GnuBook:

We also have a demonstration of the GnuBook reader without the Carousel navigation here.

Enjoy! (And be sure to check out a 2008 Google Summer of Code project for a Sugar app book viewer by Aleksander Kalev!)
