1. Legacy Data

2. From the 2011 EOL Science Review Team Report “The EOL effort to rescue and digitally archive historical field data that are presently stored in older paper, chart, and tape formats will be an extremely valuable information asset for research requiring long-term records.” “Continue progress toward and maintain a priority for making current and historical field data easily accessible”
