What has changed in the digital edition, most recent first.
- Who wrote the encyclopedia: every signed entry now names its author (1,684 contributors, 98.96% of entries attributed, each with its evidence), with an index of authors, a page for each, the editorial staff of every volume, printed column references for citation, the original printed pages beside each entry, and the data free to download.
- About 650,000 links between articles, including links to the exact section where a subject is treated (the Council of Trent inside TRENTO), and search that finds those sections.
- More than 12,000 old or mistyped addresses now lead to the right article.
- Save articles to a personal list, with sign-in by email link (no password).
- Browse by subject: the forty-one sections of the encyclopedia's own analytical index, now with their printed subsections.
- Saints of the day from the Roman Martyrology, a month-by-month calendar with feasts and fast days, and an optional daily email.
- All twelve volumes read again with a more accurate OCR, recovering pages and articles the first reading had missed.
- The site opens: the complete Enciclopedia Cattolica (1948–1954), every article in the Italian original with an English translation.
