76. The listed magnitude is taken from Odewahn & Aldering, 1988ApJ...327...89O
  89. Re-inspection of the spectral plot communicated by Usher et al.
  89.  (1983ApJ...269...73U) indicates a spectroscopic classification of A or F
  89.  star, not a DA white dwarf.
 295. The listed magnitude is taken from Koo et al. (1986AJ.....91..478K).
 296. The finder chart and position for object 1305+2802 in Borra et al.
 296.  (1996AJ....111.1456B) are not consistent. The identification of 1305+2802
 296.  with US 296 is based on the position coincidence between the two objects.
 296.  Either the finder chart of Borra et al. (1996AJ....111.1456B) is in error
 296.  and the position and match with US 296 are correct (the choice used here)
 296.  or the position is in error and there is no match with US 296.
 313. The listed magnitude is taken from Treyer et al. (1998MNRAS.300..303T).
 330. Koo et al. (1986AJ.....91..478K) measure this object to be a small
 330.  amplitude variable with ultraviolet excess; they indicate a spectroscopic
 330.  classification of ``star (probably subdwarf).'' Treyer et al.
 330.  (1998MNRAS.300..303T) classify this object as a quasar, and this is the
 330.  classification used here.
 353. Darling & Wegner (1994AJ....108.2025D) give a spectroscopic classification
 353.  of NHB; a spectrum by the present authors indicates a spectroscopic
 353.  classification of DA white dwarf, consistent with the classification
 353.  given by Koo et al. (1986AJ.....91..478K).
 406. Wegner & McMahan (1988AJ.....96.1933W) classify this object as a sdOB ;
 406.  star; a spectrum by the present authors unambiguously shows this object
 406.  to be a quasar.
 440. A corrected Bmag magnitude is listed. The need for a corrected Bmag
 440.  magnitude, position, and finder chart is noted in Appen. C, Table C1.
 454. Maxfield et al. (1995PASP..107..566M) report an uncertain classification
 454.  of "star (G?)" for this object; a spectrum by the present authors
 454.  indicates a spectroscopic classification of DA white dwarf, in agreement
 454.  with the observation of Reboul et al. (1987A&A...177..337R).
 527. A correction to the published finder chart is noted in Appen. C, Table C1.
 592. The listed magnitude is taken from Berger et al. (1991A&AS...87..389B). A
 592.  correction to the published finder chart is noted in Appen. C, Table C1.
 966. Usher et al. (1983, in Proc. 24th Liege Int. Astrophys. Colloq.,, 245) 
 966.  give this object an uncertain classification of ``star?''. A spectrum by 
 966.  the present authors indicates that this objects is more likely a quasar, 
 966.  but the classification is still uncertain.
1015. Molthagen et al. (1997A&AS..126..509M) identify this object as a
1015.  BL Lacertae object, with no redshift reported.
1022. This object was observed spectroscopically by the present authors to
1022.  confirm an identification given by the referee of the Mitchell et al.
1022.  (1984ApJ...287L...3M) paper.
1450. A correction to the published finder chart is noted in Appen. C, Table C1.
1889. Nass et al. (1996A&A...309..419N) identify this object as a BL Lacertae
1889.  object, with no redshift reported.
2230. The need for a corrected position and finder chart is noted in Appen. C,
2230.  Table C1.
2504. Usher et al. (1983, in Proc. 24th Liege Int. Astrophys. Colloq.,, 245)
2504.  provide an uncertain spectroscopic ID as a quasar with z=0.1. The object
2504.  was identified as a BL Lacertae object, with no redshift reported, by
2504.  White et al., 2000ApJS..126..133W. A spectrum by the present authors also
2504.  indicates an uncertain spectroscopic ID as a quasar, with a corresponding
2504.  uncertain redshift that is reported in this table.
2566. This object is a cool DA while dwarf, with estimated type of ~DA7. It has
2566.  been given a ``rs'' spectroscopic ID because such cool stars are not
2566.  expected to exhibit B-UVX colors on the US plates.
2751. A correction to the published finder chart is noted in Appen. C, Table C1.
2772. A correction to the published finder chart is noted in Appen. C, Table C1.
2910. The position reported in Wagner et al. (1988AJ.....96.1933W) is in error.
2910.  A corrected B_US_ magnitude is listed (see Appen. C, Table C1).
2964. A correction to the published finder chart is noted in Appen. C, Table C1.
3133. This object was originally cataloged in the edge zones (IER) of the survey
3133.  field centered on SA 94. It has been reassigned to the central zones
3133.  (see Appen. C).
3250. Wegner et al. (1987AJ.....94.1271W) give a spectral classification of NHB;
3250.  a spectrum by the present authors indicates a very hot, weak-lined star.
3273. The position reported in Darling & Wegner (1996AJ....111..865D) is in
3273.  error. The object match was accomplished through the Kiso finding chart 
3273.  in Kondo et al. (1980AnTok..18...55N). This object appears in the white 
3273.  dwarf list of Gemmo at al. (1993, in White Dwarfs: Advances in 
3273.  Observation and Theory); Mitchell (1998ApJ...494..256M) and Darling & 
3273.  Wegner (1996AJ....111..865D) classify this object as a sdB star.
3289. Wegner & McMahan (1988AJ.....96.1933W) classify this object as a NHB star;
3289.  Gemmo at al. (1993, in White Dwarfs: Advances in Observation and Theory)
3289.  list it as a white dwarf; Mitchell (1998ApJ...494..256M) classifies this
3289.  object as a sdB star.

3450. A correction to the published finder chart is noted in Appen. C, Table C1.
3461. A correction to the published finder chart is noted in Appen. C, Table C1.
3470. Wegner et al. (1987AJ.....94.1271W) indicate a ``featureless spectrum'';
3470.  Barbieri & Cristiani (1986A&AS...63....1B) list it as a probable white
3470.  dwarf; Mitchell (1998ApJ...494..256M) classifies this object as a sdB 
3472. star Wegner et al. (1987AJ.....94.1271W) indicate a ``featureless 
3472.  spectrum''; spectroscopic references 1, B, H, and L all classify this 
3472.  object as a quasar.
3611. Green et al. (1986ApJS...61..305G) give this object an uncertain

3700.  classification of F star.
