Notebooks for this project contain shotlists for video shot at Staten Island Clay Pit Ponds State Park, the Bronx River waterfall, the World Trade Center tapes, and saplings at Inwood Hill Park in Manhattan.

Although most of the other environmental projects documented in this series involved the use of video, apart from "Nature in New York City," their documentation does not include video recordings. Records for NEST include correspondence, notes, a petition, and other records documenting an advocacy movement to dedicate a cable access channel to the environment. Records for include notes and photographs used in the publication. Tapping on Water is documented with a proposal, an artist statement, and a shotlist.
