From the e-ZISS website:
The e-ZISS digital critical editions of Slovenian literature offer selected Slovenian texts with integrated facsimiles, transcriptions and scholarly commentary, in some cases including audiovisual recordings.
The e-ZISS project strives to create a synthesis of three components. The first one is the tradition of Slovenian literature, reaching from medieval manuscripts and folk songs to works of literary art. The second component is ecdotics – the tradition of philological study of texts and their presentations in critical editions. The third component is modern information technology… Digital critical editions do not supersede classical printed editions, but offer several additions, and a way to a more varied reader’s reception.
There are a number of items at the site, but the one my correspondent Paul alerted me to is particularly striking, the Freising Manuscripts:
The Freising Manuscripts are the earliest document of Slovenian culture. They are the earliest preserved writings in Slovenian as well as the earliest Slavic texts, written in the Latin alphabet….
The present edition offers a historical overview of the most important scholarly editions of the Freising manuscripts. It contains several diplomatic, critical and phonetic transcriptions and translations of the manuscripts into Latin and five modern European languages. This edition also contains a series of studies and commentaries, a glossary of the words used in the manuscripts, a bibliography and other appendices. The electronic edition is also enriched with a spoken reconstruction in early Slovenian, integrated with the transcription of the manuscripts eg. in modern Slovenian.
Even if you have no particular interest in Slovenian, the presentation of text in facsimile and various transcriptions and translations, with glossary and other apparatus, is exemplary, and I hope to see this kind of thing become more and more common.
