cds-question@unistra.frastrometryeclipsing-binary-starsspectroscopic-binary-starsspectroscopyo-starssurveysMultiplicity in massive stars is a key element to understand the chemical and dynamical evolution of galaxies. Among massive stars, those of O type play a crucial role due to their high masses and short lifetimes. MONOS (Multiplicity Of Northern O-type Spectroscopic systems) is a project designed to collect information and study O-type spectroscopic binaries with {delta}>20{deg}. In this first paper we describe the sample and provide spectral classifications and additional information for objects with previous spectroscopic and/or eclipsing binary orbits. In future papers we will test the validity of previous solutions and calculate new spectroscopic orbits. The spectra in this paper have two sources: the Galactic O-Star Spectroscopic Survey (GOSSS), a project that is obtaining blue-violet R~2500 spectroscopy of thousands of massive stars, and LiLiMaRlin, a library of libraries of high-resolution spectroscopy of massive stars obtained from four different surveys (CAFE-BEANS, OWN, IACOB, and NoMaDS) and additional data from our own observing programs and public archives. We also use lucky images obtained with AstraLux. We present homogeneous spectral classifications for 92 O-type spectroscopic multiple systems and ten optical companions, many of them original.We discuss the visual multiplicity of each system with the support of AstraLux images and additional sources. For eleven O-type objects and for six B-type objects we present their first GOSSS spectral classifications. For two known eclipsing binaries we detect double absorption lines (SB2) or a single moving line (SB1) for the first time, to which we add a third system already reported by us recently. For two previous SB1 systems we detect their SB2 nature for the first time and give their first separate spectral classifications, something we also do for a third object just recently identified as a SB2. We also detect nine new astrometric companions and provide updated information on several others. We emphasize the results for two stars: for {sigma} Ori AaAbB we provide spectral classifications for the three components with a single observation for the first time thanks to a lucky spectroscopy observation obtained close to the Aa,Ab periastron and for {theta}^1^ Ori CaCb we add it to the class of Galactic Of?p stars, raising the number of its members to six. Our sample of O-type spectroscopic binaries contains more triple- or higher-order systems than double systems.2019A&A...626A..20Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/626/A20CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/274 : Galactic O-Star Spectroscopic Survey (GOSSS) (Sota+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/626/A20https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/626/A20http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/626/A20https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/626/A20https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/626/A20http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/626/A20GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/626/A20/tablea2 (Coordinates and spectral classifications)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/626/A20/tablea2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/626/A20/tablea2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/626/A20/tablea2?GETtext/xml+votable180.050000true270.46782917-19.106130560.0055555555555555566/1299 1302 2409 2806 3066 3214 3283 3301 3307-3308 3337 3430 3585 3648 3755 12943 13281 14008 14237 14263 14267 14619 14623 14630-14632 14641 14644-14646 14653-14654 14690 14692-14693 14719 15369 15478 15625 21438-21439 21635 21647 22088 22240 22249 22253 22258 22854 22884 23637 24496 24555 29095 29098 29111 29118 29162 29463 29513 29537 30627https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/626/A20?format=asciidefaultJ/A+A/626/A20/tablea2Coordinates and spectral classificationsSimbadNameSimbad column added by the CDSmeta.idcharNameObject namemeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
