These galaxies have been selected on their Ly{alpha} (73), [OII] (285), H{beta}/[OIII] (387) or H{alpha} (362) emission line, and have been classified with optical to near-infrared colours. A subsample of 98 sources have reliable redshifts from multiple narrow-band (e.g. [OII]-H{alpha}) detections and/or spectroscopy. In this survey paper, we present the observations, selection and catalogues of emitters. We measure number densities of Ly{alpha}, [OII], H{beta}/[OIII] and H{alpha} and confirm strong luminosity evolution in star-forming galaxies from z~0.4 to ~5, in agreement with previous results. To demonstrate the usefulness of dual-line emitters, we use the sample of dual [OII]-H{alpha} emitters to measure the observed [OII]/H{alpha} ratio at z=1.47. The observed [OII]/H{alpha} ratio increases significantly from 0.40+/-0.01 at z=0.1 to 0.52+/-0.05 at z=1.47, which we attribute to either decreasing dust attenuation with redshift, or due to a bias in the (typically) fibre measurements in the local Universe that only measure the central kpc regions. At the bright end, we find that both the H{alpha} and Ly{alpha} number densities at z~=2.2 deviate significantly from a Schechter form, following a power law. We show that this is driven entirely by an increasing X-ray/active galactic nucleus fraction with line luminosity, which reaches ~=100 per cent at line luminosities L>=3x10^44^erg/s.2017MNRAS.471..629Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/471/629CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/471/629https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/471/629http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/471/629https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/471/629https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/471/629http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/471/629GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/471/629/tablec1 (List of sources that are observed as dual-emitters (line-emitters in at least two narrow-bands))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/471/629/tablec1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/471/629/tablec1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/471/629/tablec1?GETtext/xml+votable180.050000true218.3333.57540.005555555555555556Cone search capability for table J/MNRAS/471/629/tabled1 (Catalogue of NB392 line-emitters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/471/629/tabled1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/471/629/tabled1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/471/629/tabled1?GETtext/xml+votable180.050000true217.94533.310.005555555555555556Cone search capability for table J/MNRAS/471/629/tabled2 (Catalogue of stV line-emitters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/471/629/tabled2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/471/629/tabled2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/471/629/tabled2?GETtext/xml+votable180.050000true218.23933.30520.005555555555555556Cone search capability for table J/MNRAS/471/629/tabled3 (Catalogue of NB501 line-emitters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/471/629/tabled3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/471/629/tabled3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/471/629/tabled3?GETtext/xml+votable180.050000true217.63533.36640.005555555555555556Cone search capability for table J/MNRAS/471/629/tabled4 (Catalogue of NB921 line-emitters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/471/629/tabled4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/471/629/tabled4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/471/629/tabled4?GETtext/xml+votable180.050000true217.41733.55890.005555555555555556Cone search capability for table J/MNRAS/471/629/tabled5 (Catalogue of NBH line-emitters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/471/629/tabled5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/471/629/tabled5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/471/629/tabled5?GETtext/xml+votable180.050000true218.34533.26480.005555555555555556Cone search capability for table J/MNRAS/471/629/tabled6 (Catalogue of NBK line-emitters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/471/629/tabled6?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/471/629/tabled6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/471/629/tabled6?GETtext/xml+votable180.050000true218.0833.26140.0055555555555555566/9146-9147 9150 10513https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/471/629?format=asciiOpticalInfrareddefaultJ/MNRAS/471/629/tablec1List of sources that are observed as dual-emitters (line-emitters in at least two narrow-bands)recnoRecord number assigned by the VizieR team.
