The BookReader was developed by the Internet Archive and open source contributors to provide online access to scanned books. The Internet Archive has more than 1,000,000 scanned books available to read online. The BookReader is also used to provide access to materials from many other organizations.

Accessing the BookReader on Open Library Look for the Read Online links or the open book icon

to open a book in the BookReader. You can search for available books by

checking the "Only show eBooks" checkbox in the Open Library search.

Accessing the BookReader on the Internet Archive To use the BookReader, click on the "Read Online" link on the left side of an archive.org details page.

Download source code The BookReader source code is available in the openlibrary.org github repository. Click here to access the source code using git.. You can also just download the latest release.

BookReader demo Once you've downloaded the source code you can open BookReaderDemo/index.html in your web browser and you should see an example book. To use your own images you would modify BookReaderJSSimple.js to connect the BookReader with your book's page images and metadata.

Embed example For books hosted on the Internet Archive the BookReader can be embedded on any site that allows you to add an iframe, for example using the code below. openlibrary.org/dev/docs/bookreader

Simple access control

Serving Images In the case of the Standalone Demo, operation is fairly simple. Images are numbered sequentially and stored in a directory called "StandAloneImages". The images are all the same size, and two functions in BookReaderJSSimple.js, getPageWidth() and getPageHeight(), return the page size. Scaling is done in the web browser. For books scanned by the Internet Archive and stored on archive.org, bookreader operation is a bit more complex. During the book scanning process, each page is imaged using a high-resolution digital camera, and then each page is cropped and deskewed. The size of the cropped image is stored in a file called scandata.xml. During this process, some images, such as color cards, white cards, and tissue paper pages, are marked as pages that should not be displayed. This information is also stored in scandata.xml. The cropped and deskewed images are stored in JPEG 2000 format in a zip file called bookid_jp2.zip. The raw images, the cropped and deskewed images, and the scandata.xml file are available for each book on archive.org. Because crop boxes can vary between pages for Internet Archive books, the getPageWidth() and getPageHeight() functions can return a different size for each image in the book. Also, since some pages are not supposed to be displayed, the getPageURI() function maps an "index number" that the book reader uses to a "leaf number" that corresponds to an image in the jp2.zip file. These functions use information from scandata.xml to determine size and url for each page. Because web browsers generally cannot display JPEG2000 images, a piece of code called BookReaderImages.php performs onthe-fly JPEG2000 to JPEG conversion on the archive.org cluster. For efficiency, this code also provides server-side image scaling and other image processing. More information on how BookReaderImages.php works.

Testing and Release Process Bugs and feature requests against the BookReader can be filed in the BookReader Launchpad Bug Tracker. During development features and bugs in progress are targeted to the next milestone. Once all the bugs for the milestone are in the "Triaged" status and ready to test the code is given to QA for testing. Since Launchpad does not have separate QA bug statuses we use the tags "needs-qa", "qa-verified" and "qa-reopened" to designate bugs that are ready for testing, verified by QA or have problems with the fix. Code in progress on a development milestone branch may be pushed to our openlibrary/BookReader GitHub account on that branch. Once the release candidate has been approved by QA it is pushed out to GitHub on the branch and also merged into master. The branch point is tagged with the release name which will automatically make it appear on our BookReader GitHub downloads page. Unit Testing The BookReader is starting to have unit tests, written in QUnit. We are setting up a BookReader TestSwarm server.

Extending bookreader functionality To make is it easier to work with other sources, the bookreader can expect a book interface from the client with the following methods. getPageCount() getPage(index) getPageWidth(index) getPageHeight(index)

The book reader can have optional functionality which is enabled only when the book implementation has a specific method defined. For example, bookmarks functionality can be enabled only when the book interface has getBookmarksmethod defined. getBookmarks(index)
