本文给出了33个红移大于3.1的类星体的测光和高信噪比中分辨率光谱的统一方法。样本包括17个新发现的类星体（其中两个红移超过4.4）和16个来自文献的来源。这个样本中的天体的r星等在17.4到21.4之间;它们的光度在-28.8到-24.9之间。33个天体中有3个是宽吸收线类星体。发现了一些可能的高红移阻尼Ly-alpha系统。参考文献42。
A uniform set of photometry and high signal-to-noise moderate resolution spectroscopy of 33 quasars with redshifts larger than 3.1 is presented. The sample consists of 17 newly discovered quasars (two with redshifts in excess of 4.4) and 16 sources drawn from the literature. The objects in this sample have r magnitudes between 17.4 and 21.4; their luminosities range from -28.8 to -24.9. Three of the 33 objects are broad absorption line quasars. A number of possible high redshift damped Ly-alpha systems were found. 42 refs.
