Add to ORKGWe present the results of long-slit CCD spectroscopy on 39 objects and four close companions from the University of Michigan objective-prism survey lists. Twelve of them are quasars with redshifts ranging from 0.326 to 2.852, and an additional 12 objects (including companions) are Seyferts or active galaxies ranging in redshift from 0.0365 to 0.227. UM 443 may be a broad absorption-line quasar. UM 565 is a star with a puzzling spectrum. Spectra are presented for a total of 25 objects
