Comments:

1. MinII = 11.35, D = 0.07 P. X-ray source 1RXS J000618.5+694817.

2. Twice shorter period and type RRC are possible. MinII = 13.35. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

3. MinII = 13.5. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

4. MinII = 13.2. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

5. MinII = 14.9. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

6. MinII = 11.9. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

7. MinII = 13.8. Faint close companion 2MASS 06100589+6959121 .

8. MinII = 14.5. A fainter close companion GSC 4407-00850, the amplitude of variability is underestimated.

9. D = 0.16 P. X-ray sources 1WGA J1333.3+5030 = XBS J133321.2+503102. Identification with the X-ray source 1RXS J133318.5+503105 is possible.

10. MinII = 13.35:, D = 0.12 P. O'Connell effect.

11. MinII = 14.0. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

12. MinII = 12.8, D = 0.16 P. Faint close companion GSC 2755-01037, the NSVS amplitude is slightly underestimated. Identification with the X-ray source 1RXS J230903.5+324634 is not excluded.

13. MinII = 11.82. Period P = 0.3632 days is not excluded. The ROTSE data with photometric correction flags (usually rejected) were kept for the analysis.

14. MinII = 14.6.

Remarks:
I present the discovery of 14 new eclipsing binaries. A search for variables was carried out in the publicly available data of the Northern Sky Variability Survey (NSVS, Wozniak et al., 2004, also see http://skydot.lanl.gov/nsvs). These observations were analyzed using the period-search software developed by Dr. V.P. Goranskij for Windows environment. The coordinates were drawn either from the Tycho-2 or 2MASS catalogs.
