Noticed a couple of weblogs with a focus on (heritage) preservation.

World Heritage Forum
From the weblog:

This website is made to exchange information on UNESCO World Heritage issues.

HangingTogether
From the weblog:

HangingTogether is a place where some of the staff at RLG, a membership organization of libraries, archives, and museums, can talk about the intersections we see happening between these three different types of institutions. We travel to our members a lot and go to conferences and wanted to be able to take note of the interesting things we see along the way. Stop in, stay awhile, and hang out.
