Infrastructure tools to support an effective radiation oncology learning health system

The Indo-European Etymological Dictionary (commonly abbreviated IEED) was a research project of the Department of Comparative Indo-European Linguistics at Leiden University, initiated in 1991 by Peter Schrijver and others. It was financially supported by the Faculty of Humanities and Centre for Linguistics of Leiden University, Brill Publishers, and the Netherlands Organisation for Scientific Research.^[1]

The IEED project was supervised by Alexander Lubotsky.^[2] It aimed to accomplish the following goals:

• to compile etymological databases for the individual branches of Indo-European, containing all the words that can be traced back to Proto-Indo-European, and print them in Brill's Leiden Indo-European Etymological Dictionary series,
• to publish those databases free of charge electronically on the Internet, by utilizing Sergei Starostin's STARLING software technology,^[3]
• finally, once the etymological dictionaries of the individual branches have been compiled, to create a new large Indo-European etymological dictionary that will serve as a replacement of Julius Pokorny's outdated but still valuable Indogermanisches etymologisches Wörterbuch.
