Introduction

The problem of creating large, homogeneous and deep samples of actively star-forming low-mass galaxies is very important for several applications in studies of galaxy evolution and spatial distribution. Several earlier projects, like the Second Byurakan Survey (SBS) (Markarian et al. [1983], Stepanian [1994]), the University of Michigan (UM) survey (e.g., Salzer et al. [1989]), and the Case survey (Pesch et al. [1995], Salzer et al. [1995], Ugryumov et al. [1998]), as well as some others, identified on objective prism plates many hundreds of emission-line galaxies. The Hamburg/SAO survey (HSS) is intended to create a new very large homogeneous sample of such galaxies in the region of the Northern sky with an area of some 1700 square degrees. The basic outline of the HSS and first results are described in Paper I (Ugryumov et al. [1999]), while additional results from follow-up spectroscopy are given in papers II, III and IV (Pustilnik et al. [1999], Hopp et al. [2000], Kniazev et al. [2001a]). In this paper we present the results of follow-up spectroscopy of another 209 objects selected on the Hamburg Quasar Survey (HQS) prism spectral plates as ELG candidates.

The article is organized as follows. In section 2 we give the details of the spectroscopic observations and of the data reduction. In section 3 the results of the observations are presented in several tables. In section 4 we briefly discuss the new data and summarize the current state of the Hamburg/SAO survey. Throughout this paper a Hubble constant H₀ = 75 km$\,$s^-1 Mpc^-1 is used.
