FUJIWARA no Teika left another personal collection "Hyakunin Shuka" (The Outstanding Waka by a Hundred Pests); the big difference with "Ogura Hyakunin Isshu" is two things: It doesn't choose Emperor Gotoba nor Emperor Juntoku, while choosing FUJIWARA no Teishi (Sadako), MINAMOTO no Kunizane (Kuninobu) and FUJIWARA no Nagakata; the tanka by MINAMOTO no Toshiyori is different one (in "Ogura Hyakunin Isshu" his tanka begins with "Ukari-keru").
関連書に、やはり藤原定家の撰に成る『百人秀歌』があり、百人秀歌と百人一首との主な相違点は「後鳥羽天皇・順徳天皇の歌が無く、代わりに藤原定子・源国信・藤原長方の3名が入っている」「源俊頼の歌が『うかりける』でなく別の歌である」2点である。
