Overview
This monumental reference work, complete in ten volumes, is the authorized and unabridged translation of the famous Theologisches Wörterbuch zum Neuen Testament—considered by many scholars to be the best New Testament Dictionary ever compiled. Mediating between ordinary lexicography and the specific task of exposition, TDNT (published by Eerdmans) treats more than 2,300 theologically significant New Testament words, including the more important prepositions and numbers as well as many proper names from the Old Testament. Presenting the words in the order of the Greek alphabet, TDNT typically discusses the following for each word: its secular Greek background, its role in the Old Testament, its use in extrabiblical Jewish literature, and its varied uses in the New Testament. Substantial bibliographies and footnotes supplement the articles.

One of the most widely-used and well-respected theological dictionaries ever created, TDNT is indispensable for studies in the Greek New Testament and theology. Words were selected for inclusion in this dictionary based on their theological significance. The historical development and theological nuances of each word are exhaustively explored. The authors trace usage in classical Greek literature, the Old Testament (LXX) and extrabiblical texts, and New Testament passages.

Key Features
Abbreviations, a commonly cryptic element of most theological works, can now be clicked upon in Logos, and the user will be provided with the full abbreviation definition from the abbreviation table.
References to both The Works of Philo and The Works of Josephus are enabled. Therefore, if versions of Philo or Josephus are available to the user, these valuable cross references can be examined in their complete context.
The indices of volume ten have been implemented as topic indices within Logos. Specifically:
The Index Greek Keywords included information that associates Strongs’ numbers with Greek articles. This information is implemented as a topic index. This allows the user to use a Strongs-number enabled New Testament (such as the King James Version or New American Standard Bible, 1995 Edition) to access the information in TDNT from a Strongs number.
Individual Greek article headwords are included as topics in both Greek and Greek Lemma languages. This allows the user to use the Keylink functionality to jump to articles in TDNT from a morphologically tagged Greek text.
The Index of English Keywords is also available. This allows the user to search TDNT in English for a given topic and arrive at the relevant Greek articles.
The Contributor and Co-Worker Index is also available. A comprehensive list of articles from a contributor is available simply by clicking on the author citation at the end of each article.
The Index of Biblical References is comprehensive in this electronic version. Using the Reference Search functionality, one can arrive at a complete listing of instances where a particular verse is referenced throughout the whole of the TDNT.
All Bible references are enabled, allowing the user to click upon a Bible reference to look up the reference in a preferred translation. In addition, discrepancies in versification are automatically dealt with. So, when a verse reference to the Septuagint (LXX) is made, any versification differences are implicitly rectified when the search results are reported back to the user.
Article references by either article name or by volume and page are enabled as well. This allows the user to examine the numerous instances where a given article refers the user to another article within TDNT for clarification and expansion on a given topic or idea.
