A Description of the Pacific Fisheries Information Network (PacFIN) from 1981-1996 is available as a PDF or Link to external site. The report is a little older, but contains valuable information on the PacFIN system. While the structure of the database and the tables have changed over time, the general data flow and content of the data is similar.
The report is a chapter in a larger report that looked at groundfish data collection and management on the west coast. The full report can be found at Link to external site
