\begintext

The ASAS-3 (Pojmanski, 2002), NSVS (Wozniak et al., 2004) and Hipparcos (Perryman et al., 1997) databases have been used to find new elements for another set of 80 eclipsing binaries. NSVS, ASAS-3 and Hipparcos data have been combined to improve the period determinations. Unfiltered NSVS ROTSE1 magnitudes were shifted to match the V magnitude of the stars. When neither ASAS nor Hipparcos observations exist, the original ROTSE1 magnitudes have been given. Hipparcos observations have been transformed to V using a table by the author published electronically in IBVS No. 5482 (Otero, 2003). Saturated data in ASAS-3 and flagged observations in the Hipparcos Epoch Photometry and the NSVS dataset were discarded.
The candidate stars were selected from the NSV catalogue (Kukarkin and Kholopov, 1982) and its supplement (NSVS) (Kazarovets et al., 1998) and the GCVS (General Catalogue of Variable Stars, Kholopov et al., 2005). Stars in the GCVS and NSV catalogues that had no given classification or were classified as eclipsing binaries, S, L, I, CST or VAR with no spectral type published or spectral type K or earlier were also checked. This list also include new eclipsing binaries randomly found in the ASAS-3 database and not published or published with wrong elements in the ASAS catalogue (Pojmanski, 2002).
The method of bisected chords was used to determine times of minima. The accuracy depends on the quantity and quality of the observations. Elements were found with AVE (Barber\'a, 1999) and a Microsoft Excel period search utility.

Table 1 shows the list of variables. The first column gives the variable star designation according to the GCVS or the GSC number if the star is not a known variable star. The following columns give another identifier; the brightness range of the variable (V= ASAS-3 V magnitudes; *= ROTSE1 magnitudes), with the magnitude of secondary eclipse between brackets; the epoch of minimum light derived from the complete dataset; the period; the variability class and the spectral type with a note to the spectral type source.
