  • World Public Library has made more than 1,000 eBooks freely available to the public specifically gathered for OLPC folks. Please visit to download the titles.

See also The OLPC literature page, with links to sites offering collections of free (Public Domain out-of-copyright) and commercial Ebooks in many languages. There are also specific book collections being developed by libraries and archives for OLPC (add your own!).


A "digital book" is a book that is stored in a computer and read on a computer screen. These are sometimes called "ebooks", but we refer to digital books simply as "books". Books are data without a reader application. (This last point is stretched somewhat by recent versions of Adobe Acrobat's PDF reader which can handle embedded Javascript applications in a PDF document and for HTML files containing Javascript). There is a place for rich documents containing their own reader code, but these blur the line between activities with lots of data and books as such.

Digital book formats

Book formats should be compressed (to conserve space) and open. In particular, they must not be encumbered by patents, and must be inclusive - they should not favor any particular vendor.

See wikipedia:Comparison of e-book formats for a more comprehensive list.


EPub is a free standard for reflowable content, which lets a reading device determine how it gets displayed. It uses XHTML or DTBook to represent text and zip as a packaging format. It replaced the older Open eBook standard in 2007. Related subformats and standards include the Open Publication Structure (OPS), Open Packaging Format (OPF), and OEBPS Container Format (OCF).

This is the latest format supported by the Read activity, and a standard supported by fbreader and many modern ebook publishers.


Although not particularly designed as a book format, HTML is widely used for books. Most newer Project Gutenberg books are available as HTML. Both special purpose Ebook readers and web browsers can be used to access HTML Ebooks.

HTML eBook packaging formats

HTML/XHTML has basically "won" as the presentation format for commercial and newly-published eBooks. Most eBook formats are just subsets or supersets of HTML or XHTML, using standard tags like <p>, <img>, <h1>, etc.

The debate has moved on to the organization and representation of such files for offline self-contained viewing.

  • OLPC's own .xol bundle format for Collections is a download format that the Journal unpacks and adds to the Library in Browse.
  • The International Digital Publishing Forum (IDPF) promotes a .epub XML file format, see ePub demystified.
  • In that, Bill Janssen comments "On the eBabel front, let’s examine the other web site packaging formats." Googling for “web page archive format”] gives one an interesting list
    • Microsoft’s MHTML, introduced in IE 5, documented in RFC 2557, and apparently also supported by the Opera browser.
    • Apple’s WebArchive, used by Safari.
    • The Library of Congress’ WARC, which they’re using to preserve Web site captures, and is a draft ISO standard.
    • WARC is based on ARC_IA, the format used by the Internet Archive.
    • There’s also MAF, the Mozilla Archive Format for Firefox 3, Christopher Ottley’s project.
  • the WikiBrowse activity is a web server that serves content from a compressed MediaWiki dump, forming a self-contained browsable offline wikireader


XML is not a directly usable format, but rather a meta-format. XML alone is not a book format, but many modern formats that can be used for books are XML based, such as ODF, and the XHTML variant of HTML. Other XML based formats are DocBook, popular for computer manuals, or TEI, used in the Humanities. Modern web browsers can render XML directly, but to make such a display attractive some transform (expressed in CSS or XSLT) may be required.

Text / ASCII / Unicode

The most basic format, can be compressed with simple/standard compression programs if needed. Original and default format for the Project Gutenberg e-texts.

Browse and the Read Etexts activity can render text files. Read also can but it opens them for editing.


The DJVU format was developed in order to provide a much higher level of compression for scanned paper books, than existing formats like JPEG and TIFF can provide.


The PDF format is a simplified form of the Postscript programming language that only includes the commands necessary to paint ink on the page. It is easy for end users to create PDFs with the Print function of a word processing or drawing application. There are extensive Free/Open Source libraries of functions for creating, editing, and otherwise modifying PDFS, and applications built from them. For example, libpoppler and the Poppler PDF Utilities. There are also several Free PDF display programs, including xpdf, kpdf, evince, gv, and ViewPDF. The Read activity uses Evince and poppler to render PDFs.


OpenDocument is a compressed format (zip-compressed XML) for documents, including books, presentations, and spreadsheets. Complex documents (with many images) can be sent as a single document (unlike HTML), yet it can flow in a display (unlike PDF). It is also editable. The Write activity on the XO uses libAbiword and can open ODF files.


Greenstone is a self-contained bespoke format for document collections. A Greenstone library allows quick full-text search access to large collections, and is typically smaller than the full-text it contains, due to the compression scheme it uses. A Greenstone library can be both accessed via a web server or locally on a (read-only) disk. A complete Greenstone collection can be large, which makes it less useful, given the storage constraints of the OLPC.


"FictionBook is an XML format for storage of books where each element of the book is described by tags." Also known as fb2, it is supported by FBReader. In fact, the FBReader website lists other book formats that are not listed here.


DeVice Independent format. Output of a typesetting system called TeX that is very widely used in academic and open source technical literature. See wikipedia for more information.

Book Readers

On the XO


The Browse activity renders HTML, XHTML, and most image formats.

The users's home page in Browse is the "OLPC Library", which presents a navigation bar of available Collections on the XO.


The Read activity uses the Evince library to render, and has a modified UI targeted to kids. Evince supports various image file formats including DJVU, PDF, [TIFF], and DVI with appropriate library support. Read in release 8.2.0 supports primarily PDF. See choosing image formats.


The Write activity uses libAbiword which can render ODF .odt files.

Unclear if it can open them in read-only format suitable for eBook reading

Other book readers


A popular book format for PalmOS devices. A reader for Linux/X11/GTK+ already exists in the CVS codebase (and is distributed in the Plucker 1.8 source tarfile). It should run on OLPC machine's OS. Most Project Gutenberg books are already available in Plucker format at the URL

where NUMBER is the PG book number for that book. For instance, John Stuart Mill's autobiography is available from PG in Plucker format as
