The spectroscopic criteria for identifying strong-lined DA-type stars on low-dispersion objective prism plates are reviewed, as are the objective prism surveys made to date with discovery of white dwarfs a partial or major objective (Table I). It is claimed that there may be upwards of 100 undiscovered white dwarfs brighter than B magnitude 14.0. Some data for all the white dwarfs so far discovered by objective prism are collected in Table II; new identification charts are given for two of these.
