The PHBR (Player's Handbook Reference) series is one of the most highly-regarded, and yet much-maligned, series of supplements ever created. Each sourcebook takes one of the races or classes of the AD&D game, and adds to it huge amounts of new detail - new equipment, spells, kits (sub-classes), lore, new rules, etc. The problem is that the players love these so much that the DM often feels compelled to buy into the rest of the series - an expensive proposition! Fortunately, these works were "reprinted" in the excellent AD&D Core Rules CD-ROM. This one has details on the creation and development of Paladins, with chapters including: Paladin requirements, level advancement, armor, weapons, magic, special powers (including a full description of the Aura of Protection), honor, kits (with such great examples as the Divinate, Inquisitor, Skyrider, and Wyrmslayer), proficiencies, equipment, role-playing, faith and divinities, holy orders, and more! A great book.
