The Biographisch-Bibliographisches KirchenLexicon site is no more. Or, what comes to the same thing, has vanished behind a paywall.
It was free from 1996 until this year. From 2011 they asked for voluntary donations to fund the work, with little response. So now they have imposed a pay wall.
It’s not very clear why they suddenly need to monetise the site. It looks rather as if the decision was a commercial one. Bautz.de seems to be a publisher, with all that this implies.
But … there goes one of the very few worthwhile internet sites in the German language. Oh well.
