Types and sources of publications

Abstracts are short summaries of scientific findings presented at technical conferences and meetings. Many abstracts are from conference or meeting proceedings such as the Geological Society of America (GSA), National Groundwater Association (NGWA), or the Austin Geological Society (AGS).

Data Series Reports contain basic data, with brief discussions of data, but does not contain significant interpretations. These are mostly BSEACD documents.

Reports are stand-alone technical documents that provide data and interpretations. These are generally produced by agencies like the BSEACD, US Geological Survey (USGS), City of Austin (COA), and the Texas Water Development Board (TWDB).  Some reports are done by consulting agencies such as HDR, Inc., or Southwest Research Institute (SWRI).

Papers are technical documents that provide data and interpretations usually within a collection of other related technical papers. These papers are often presented at conferences and found within meeting proceedings such as the Gulf Coast Association of Geological Societies (GCAGS), Austin Geological Society (AGS), or other sources.

Posters are technical summaries of scientific findings presented with an abstracts and key figures. Posters are often presented at conferences, but only abstracts are generally published in proceedings.
