I've come across two websites for Italian literature scholars in recent weeks. Here they are:
World of Dante - from the Institute for Advanced Technologies in the Humanities (IATH). From their press release:
"The new site includes includes the Italian text and Allen Mandelbaum’s translation of the Divine Comedy marked up in XML; an interactive timeline; a gallery of more than 600 images; an array of maps of Dante’s Italy and all three realms of the afterlife; musical recordings of the liturgical chants and hymns mentioned in Purgatory and Paradise; a searchable database; and
teaching resources and activities. The new site offers a dynamic analytical tool that we hope will accommodate a wide range of approaches to teaching Dante."
Biblioteca italiana - From the Univ. di Roma La Sapienza. This website offers access to digital versions (both XML and HTML) of more than 1700 works of Italian literature, as well as to digital facsimiles of the works published in Laterza's series "Scrittori d'Italia".
Within the "Biblioteca" rubric, you can either access the full text of the works, or do textual research by searching for specific words or phrases (limiting by author, title, period, genre, or within the entire corpus). Select the HTML version for a format for reading.
Within the "Collezioni speciali" section, click on "Scrittori d'Italia" to gain access to the facsimiles of these editions. In this section, you cannot search for individual words, but you can go directly to specific chapters or pages.
