Browsing: the site is in a state of flux. For some towns, the records may be accessed in a format resembling the actual microfilms; several years or categories (birth, marriage, etc.) that must be ‘scrolled’ through sequentially, as on a microfilm reel. For others, that option is available, as well as the option to specifically view one year for one category. The latter sounds easier, but if you don’t know the exact year, scrolling the whole film may be more desirable. In either case, the images are presented in an array of small ‘thumbnail images’ that can be browsed more quickly.
Browsing: similar to the familysearch site, but directions are in Italian. A list of provinces provides easy selection at http://bitly/ItalianRecordsPortal. Categories can be separately selected.
Browsing: In my opinion, the best of the three. The categories, and indices to each category, are listed and accessible separately.
If your ancestral town’s records are on all three of these sites, you’re lucky, because records that are missing from one may well be on another. Be sure to check all three. You must embark on your own search, and sometimes learn by trial and error the idiosyncrasies of uncovering your own ancestors’ records. But it’s worth it!
