与当前项目相关的所有内容都已开放且您可以在GitHub中找到。从哪找到关键的组件的列表已在下边列出。本书的例子中用到的样例图叫做航线图（air routes），该图包括的图数据它是基于3370座机场的世界航线网络。样例图数据、大量的样例代码和更大一些的示例应用程序都可以从本书原稿在Github的项目仓库地址中找到。您也可以找到本书发行版的多种格式：如HTML, PDF文档，BocBook/XML， MOBI和EPUB，它们也是在本书原稿的Github仓库中。
样例程序包括有：独立运行的Java程序，Groovy, Python 和Ruby例子，也有很多可以从小精灵控制台运行的例子。在独立运行的程序中使用Gremlin和在控制台中使用Gremlin是有一些差异的。有例子程序说明了这两者之间的差异。样例程序域包括了完整的HTML和JavaScript的应用程序，您可以直观的可视化的探索航线图数据。GitHub项目的主页已包括在README文件中，它将帮助您导航到您的目的地网址或网页。如下是本书中各类资料的网址和链接。
All work related to this project is being done in the open at GitHub. A list of where to find the key components is provided below. The examples in this book make use of a sample graph called airroutes which contains a graph based on the world airline route network between over 3,370
airports. The sample graph data, quite a bit of sample code and some larger demo applications canall be found at the same GitHub location that hosts the book manuscript. You will also find releases of the the book in various formats (HTML, PDF, DocBook/XML, MOBI and EPUB) at the same GitHub location. The sample programs include standalone Java, Groovy, Python and Ruby examples as well as many examples that can be run from the Gremlin Console. There are some differences between using Gremlin from a standalone program and from the Gremlin Console. The sample programs demonstrate several of these differences. The sample applications area contains a full example HTML and JavaScript application that lets you explore the air-routes graph visually. The home page for the GitHub project includes a README.md file to help you navigate the site. Below are some links to various resources included with this book.

Asciidoc格式的本书原稿
• 通过Git Hub网页接口您可以查看这些文件，它们总是呈现最新的内容。
• https://github.com/krlawrence/graph/tree/master/book
Book manuscript in Asciidoc format
• This file can be viewed using the GitHub web interface. It will always represent the very latest updates.

最新版的PDF和HTML快照：
• 这些文件将有规律的更新，从而反映重要的变更。 这些是完整的发布周期之外的更新所生成的（两种）格式。PDF格式包括了分页和页码，且适用于A4纸大小。HTML网页格式的不包括上述特征。否则它们就差不多一样了。

Latest PDF and HTML snapshots
• These files are regularly updated to reflect any significant changes. These are the only generated formats that are updated outside of the full release cycle. The PDF version includes pagination as well as page numbering and is produced using an A4 page size. The HTML version does not include these features. Otherwise they are more or less identical.

本书多种格式的发行本：
Official book releases in multiple formats
• 官方发行版包括的格式有：Asciidoc, HTML, PDF, ePub, MOBI and DocBook，也有所有例子的快照和其它资料，它们都在一个包中。笔者的目标是官方发行版，大约每个月更新一次，从而提供更多新的内容以校对、补充和完善本书。 eBook 和MOBI 这两种格式是为了方便使用电子阅读器的读者，出于此目的，使用了白色的背影色以高亮显示源代码，这样便于在黑白色设备上阅读。
• Official releases include Asciidoc, HTML, PDF, ePub, MOBI and DocBook versions as well as snapshots of all the samples and other materials in a single package. My goal is to have an official release about once a month providing enough new material has been created to justify doing it. The eBook and MOBI versions are really intended to be read using e-reader devices and for that reason use a white background for all source code highlighting to make it easier to read on monochrome devices.
• 笔者推荐您使用PDF版本，因为它有页码。当然，如果您喜欢像看网页一样读书，请使用HTML格式的书。
您将不会有任何页标或者页码。如果阅读的是DocBook格式的，可以使用Linux系统中Yelp一类的工具，当然支持这一格式是为了方便您用它来生成笔者目前为止没有提供的其它的格式。目前为目MOBI和ePUB这两种格式有一个问题，它们会导致链接指向不正确的文本。除此之外，有时您需要改变字体的大小以便在设备上阅读，它们是奏效的。
• https://github.com/krlawrence/graph/releases
• I recommend using the PDF version if possible as it has page numbering. If you prefer reading the book as if it were web page then by all means use the HTML version. You will just not get any pagination or page numbers. The DocBook format can be read using tools such as Yelp on Linux systems but is primarily included so that people can use it to generate other formats that I do not already provide. There is currently an issue with the MOBI and ePub versions that causes links to have the wrong text. Other than that they should work although you may need to change the font size you use on your device to make things easier to read.
