Yesterday I got a bit ahead of myself when claiming that I had found another chunk of Dan Gillmor’s eJournal: a large amount of archival data that’s missing from 2002.
Dan has since pointed out that I’d found his regular Mercury columns, not the eJournal.
However, some further poking reveals that the Internet Archive did capture quite a number of eJournal posts from 2002 that have been presumed missing. Here’s a calendar view of 2002: there are archives from May to June, August to September, archives of November, among others. Some posts do appear to be missing, but it looks like a substantial number could be recovered.
This overview page might be helpful, too.
