Graph Databases introduces graphs and graph databases to
technology enthusiasts, developers, and database architects.

Graph Databases, published by O’Reilly Media, discusses the problems that are well aligned with graph databases, with examples drawn from practical, real-world use cases. This book also looks at the ecosystem of complementary technologies, highlighting what differentiates graph databases from other database technologies, both relational and NOSQL.

Graph Databases is written by Ian Robinson, Jim Webber, and Emil Eifrém, graph experts and enthusiasts at Neo Technology, creators of Neo4j, the world’s leading graph database.

Ian Robinson's Blog: Running the Graph Databases Book Examples
The current version of Neo4j has two different types of index: named indexes and automatic indexes. The Cypher query examples throughout the Graph Databases book use named indexes.
There's a problem, however: data created using a Cypher CREATE statement won't be indexed in a named index. This has led to some confusion for anyone wanting to code along with the examples: if you use the CREATE statements as published, the query examples won't work.
