Do you have complete and untranslated original German text of Indogermanisches Etymologisches Wörterbuch by Julius Pokorny in PDF format...?
No, we do not have the Pokorny text online. We observe copyright laws that forbid it. Copyright laws do permit "fair use" of [small] portions of a text, and on that basis we list the Pokorny head words with, e.g., their meanings expressed [by us] in English. We have, in some respects, revised the list of head words to "correct" minor mistakes therein. We are working on other extensions, for future release.
