My pal, Jenna Freedman, the Lower East Side Librarian [1] started subscribing to the Library of Congress Subject Heading Weekly list [2] (probably out of love for Libraries' great good friend and cataloger extraordinaire Sandy Berman [3]!). This week she came across a strange one [4] that I hope our readers can expound on in the comments, especially since I'm not a cataloger.

150 Electronic government information [May Subd Geog]
* 450 UF Electronic government publications [EARLIER FORM OF HEADING]
* 550 BT Government publications

Is this LC's documentation of a move away from government publications as the instantiation of our government's work toward e-government and government information as transaction? Should we be worried about this change in the heading? Is this just semantics? Is there a cataloger in the house?

The other one that I found strange was:

(C) 150 Global cooling [Not Subd Geog]
450 UF Cooling, Global
550 BT Global temperature changes

Is that some sort of Newspeak [5]?!?!
