Top 20 Books Referenced in E:CO papers

Since Volume 8 contributors to E:CO has been required to provide ISBNs for all book references. This has allowed ISCE-P to not only embed web links into the online version of E:CO, but also to more easily track which sources have been most influential (for good or for bad) with E:CO's contributors. Below are details of the Top 20 most referenced titles. The dataset for this analysis starts with Issue 8.1 (2006) and is updated each time a new issue appears. Unfortunately, different editions of the same title will have different ISBNs. This list does not take this possiblility into account and so may be biased against titles that have been published in many different formats and editions. This also means that a title may appear in the list more than once. If so, it is probably this title that should to be in the Number 1 spot. As such, this list can only be regarded as no more than a rough indicator. You can at least be sure that if you're new to complexity, the books listed below are an essential read.
