LIADA's Double Star Section presents angular separations, position angles as well as V magnitudes for 103 neglected visual double stars obtained in 2003. A total of 701 measures were averaged into 311 mean positions that range in separation from 2.6" to 225.7". Our observations were made by means of several techniques (CCD detectors, astrometric eyepieces and photographic and digital surveys). About 45% of double stars were unconfirmed pairs discovered by John Herschel which remained neglected since before 1850. BVIJHK photometry, astrometric and kinematical data were used/obtained to determine astrophysical parameters (spectral types and luminosity classes, photometric distances, etc). Their nature was determined using several professional criteria, classifying them as optical, physical or common origin pairs. Only 6% were physical double stars. New companions were added to six known systems.
