This book provides a detailed introduction to the concept of network research in archaeology as well as a guide to many specific network data management and analytical methods and models. The text of the book itself has been designed to stand alone and can be read and used without reference to any other external resources. We realize that many readers may want more guidance to help them get started doing actual analyses. To meet this need, we have created an elaborate Online Companion to the book (Peeples and Brughmans, Reference Peeples and Brughmans2022), which provides downloadable archaeological network datasets and an extensive Markdown document for the R programming language (R Core Team, Reference Pisor and Jones2021). This R Markdown document goes through examples of network data management and basic analysis techniques for all of the common methods and models covered in the book and also provides unique custom tools designed for more complex analyses such as assessments of uncertainty. Along with this, the Online Companion also contains all of the code and descriptions necessary to replicate the analyses in this book in R (or in a few cases, other software) as well as code needed to recreate data-based figures. The HTML version of the Online Companion is available at https://archnetworks.net and the raw R Markdown document and associated data, images, and code are also available on GitHub: https://github.com/mpeeples2008/ArchNetSci. These resources will be periodically updated by the authors and also include a public feedback function to allow users to ask questions, contribute data or methods, and develop resources for classroom teaching or self-teaching. We hope to build a community of active archaeological network researchers around these resources.
