Dear reader,

I announced at the top of the post that this was a "work in progress", only reflecting my own practice, a first list compiling what I use most : for ex., since I do not work on manuscripts, I only mentioned Pecia which is really good and useful when I need to find a reference. There are so many other interesting websites indeed !
Many websites are missing, and that is totally normal for the moment.
There are very few German sites, but there are few Italian, Spanish, or Belgian sites as well.
You are very welcome to inform us of web sites and pages that may help scholars and students : thus my post will be less "schlecht".
Thank you for having a little more kindness with enthusiastic young researchers.

S. Berger  lieber herr graf,

das war - soweit ich es recht verstehe - der erste eintrag von frau berger überhaupt in ihrem blog!

Danke für die motivierenden Worte.

Mannmannmann ...  archivalia wird nicht erwähnt, deswegen ist das Angebot Mist.
