Lu Bu of Book of Later Han
三國志/卷07 吕布, 张邈, 陈登, 臧洪  contains Lu Bu, Zhang Miao, [Chen Deng]], Zang Hong of the Book of the Three Kingdoms

後漢書/卷75 劉焉袁術吕布列傳 DOES NOT contains 劉焉, 
袁術(Yuan Shu), 吕布(Lu Bu) of Book of the Later Han. (WARNING zh.wikisource.org/wiki contains wrong content. 75 contains 74).

Anyway I'd like remind you that biography of Lu Bu exsist both 
at Records of the Three Kingdoms and at Book of the Later Han. However the biograpy at
Book of the later Han is longer than that of Book of 3k. 

Interestingly Record of the Three Kingdoms was said to covers 184 to 280, while Book of the Later Han said to cover from 6? to 189. Lu Bu lived 155(?) to 199. Why could Book of Later Han, which contains more detailed biography of Lu Bu, NOT be said to cover 6(?) to 200 or 220?
