The Xiaominglu 小名錄 "On childhood names" is an encyclopedia specialized on personal names written by the Tang period 唐 (618-907) scholar Lu Guimeng 陸龜蒙. Lu Guimeng's writings are collected in the book Lize congshu 笠澤叢書 (correctly, Lize congshu 笠澤藂書). The 2 juan "scrolls" long book (according to Zhao Xibian's 趙希弁 Qunzhai dushu houzhi 郡齋讀書後志, 3 juan) deals with childhood or pet names (xiaoming 小名) of historical persons, from Empress Lü 呂后, xiaoming Exu 娥姁 (r. 187-180 BCE), to Wei Youya 魏游雅, courtesy name (zi 字) Bodu 伯度, xiaoming Huangtou 黃頭 (Northern Dynasties period, 386~581). Some of the names cited are not really childhood names but intimate names (nicheng 暱稱 or niming 暱名), like Huhai 胡亥 for the Second Emperor of Qin 秦二世皇 (r. 209-207 BCE), or Xiu 秀 for Emperor Guangwu 光武帝 of the Later Han (r. 25-57 CE), or colloquial names like Arong 阿戎 for Wang Rong 王戎 or Aqian 阿謙 for Wang Sengqian 王僧謙. The book lists between 119 and 150 names, according to different sources. There must have been a 5 juan version which was probably expanded by later persons. The received version is definitely not the complete original. It is included in the reprint series Siku quanshu 四庫全書.
