EuroCom III

The EuroCom Slavic part seems to be under the work of Lew Zybatow (http://www.eurocomslav.de/). Although the Slavic portion doesn't have the clickable texts for each language at this point, and much of the website has the notice "under construction", there is a wealth of great material here for the learner who wants to systematize learning of multiple Slavic languages. Most usefully, there are some huge charts with "International Words" and "Pan-Slavic Words" as they occur in 12 Slavic languages--those are really interesting to look at. What I find really useful is the "Sound Correspondences" for the different Slavic languages. It's well-done and the animation is quite slick. You can compare different languages, and see, for example, how the word for flower illustrates typical sound changes in Russian and Czech, etc.

EuroCom II

The Germanic part of EuroCom seems to be headed up by Britta Hufeisen. However, if you go to that website (http://www.eurocomgerm.de/) and click on what used to be the accompanying material, many of the research links, the "profile words", the cognate words across the various Germanic languages, etc., you nearly always are transferred to a web page trying to sell you the book version for learning the Germanic languages (Die sieben Sieben - The Seven Sieves). I can understand that after so much effort the makers would like to get paid for their excellent work; still, they could have left some of the background material on the website, instead of just making all the links take the learner to the same "buy the book now" page.

EuroCom

The EuroCom group has done incredible work on a systematic approach to learning all the Romance, Germanic, and Slavic languages. Most of it is still free online. (They have also begun publishing books to teaching their approach). From what I can tell, Horst Klein, a German scholar in Romance Linguistics is largely responsible for the approach and for the material online for the Romance languages. Most of the learning and explanatory material is in German, although there is some in English at www.eurocomresearch.net. Let's start with the Romance material, since it appears to be the most developed (I haven't seen much for the Germanic languages, and the Slavic Languages appear to need quite some work still). They have put together a website where you can choose to learn to read Spanish, Italian, or Romanian. http://www.kom.tu-darmstadt.de/eurocom/ For each language there are more than 30 short texts, and you can click on the words in the text, and the meanings or the grammar are related to words or languages the learner may already know. There are also translations, quizzes to check comprehension, and numerous accompanying charts on grammar endings, prepositions, verbs, etc. This is an excellent resource for developing guessing skills and for systemizing the Romance roots and the grammar.
