Here are some blogs of potential interest, two from OCLC and one from JISC.
From OCLC: The Developers' Network blog
This provide updates about services which allow applications integrate OCLC services and data.
And Andrew Pace reappears in a new location: Hectic Pace
JISC now has a blog from the Information Environment Team, which, if they keep going ;-), will be a good place to look for developments in repositories, preservation and resource discovery. There will be a UK emphasis, but it should also be of general interest. No doubt, it will also be marked by 'high acronymic density'.
