EPISTEME

Episteme is a (crude) blog which automatically keeps track of changes in the preprint webpages of some people working in set theory. This version (June 2014) should be more discriminating, with fewer false positives. However the detailing/description of new eprints will be sparser.

[More explanation]

How crude is Episteme? Very! It doesn't display much context, merely making a record of changes. And it doesn't try to figure out which changes are interesting or useful.

I may tidy the contents up a bit manually, but probably not much if at all. The idea is to have some minimal mechanical notification.

Of course comments and suggestions are very welcome, but I don't promise to act on them.

Which people? Currently:
