The report is divided into two sections, one on the economy and one on the budget. One of the interesting features of the report is its first Appendix, which compares the accuracy of CBO forecasts with those of the executive Administration and the Blue Chip consensus survey. EBOs back to December 1995 are available at the Update site. Statistics surveys are available. Coverage is annual and data is available from as early as 1966 to as late as 1995.
Users have flexibility as to output layout and format.
This is a powerful, but not necessarily simple interface, and serious users should spend time with the detailed tutorials before beginning. Figures are referenced, and many of these references are available in full text from the main NSF site. Included among the images are RNA structures from the protein database at the Brookhaven National Laboratory, as well as over 250 DNA and protein structures. Sequence and descriptive information about the images is available. Non-VRML images are searchable.
