The US Census Bureau released its Information and Communication Technology (ICT) Survey: 2005
which may be of interest to some on this list. It reports hardware expenditures, which I do not find overly exciting, since I am more interested in the application of technology to problems & learning. However, I did find the expenditures by the education sector compared to other sectors noteworthy.
In 2005, the "information" sector (publishing, broadcasting, telecommunications) spent 52.4 billion and finance spent 44.2 billion. They were the top two. The education sector (which includes libraries) spent 3.7 billion and is was listed 11th out of the 19 industry categories.
There is more detail in this report that others may find of interest, but I haven't had much of a chance to delve in and review it all.
