  The field of web archiving provides a unique mix of human and automated
agents collaborating to achieve the preservation of the web. Centuries old
theories of archival appraisal are being transplanted into the sociotechnical
environment of the World Wide Web with varying degrees of success. The work of
the archivist and bots in contact with the material of the web present a
distinctive and understudied CSCW shaped problem. To investigate this space we
conducted semi-structured interviews with archivists and technologists who were
directly involved in the selection of content from the web for archives. These
semi-structured interviews identified thematic areas that inform the appraisal
process in web archives, some of which are encoded in heuristics and
algorithms. Making the infrastructure of web archives legible to the archivist,
the automated agents and the future researcher is presented as a challenge to
the CSCW and archival community.
