This table summarizes the current availability, through Gopher or WWW of documented datasets (i.e., data plus metadata) across the LTER Network. Web access to site information servers is via the “Sites” link (http://lternet.edu/ about/sites/menu.htm) from the Network Office home page (http://lternet.edu,), and Gopher access via “8. LTER Site Information Servers/” from the main LTER Gopher menu. Sites often have additional, proprietary data available to site researchers, some of which may be available on a per-case basis to others on request. In addition, descriptions or documentation are frequently online for such data. This table is not intended to provide any indication of the quantity or scope of the data available, nor does it reflect spatial or temporal extent.

Methodology
In order to ensure the continued manageability of the LTER Online Datasets Table, general categories of data were used. These categories will subsequently be created, divided or merged, if necessary, to maintain its usefulness and manageability. A few comments regarding the categories are warranted:
- Parenthetical modifiers are optional, e.g., "soil (water) chemistry" includes both "soil chemistry" and "soil water chemistry."
- Entries under the "animal" category include species lists, species abundance, individual organism measurements (e.g., weights, sizes).
- Entries for "primary production/biomass" include proxy measurements such as basal area, diameter, etc.
- Entries for "atmospheric deposition" include precipitation chemistry, as well as wet, bulk, and dry deposition.
- There is overlap for the "disturbance effects" and "fertilization effects" categories, with an entry in the latter being equivalent to an automatic entry in the former.
