      Most of the kokugos lead with the imperial seal sense. I wouldn't assume it's that rare a meaning.

      There is an entry in this dictionary for 霊璽簿, "Book of Souls (in the Yasukuni Shrine)"/"book of the dead".

The last kanji is 簿 "register, record book", so I wondered what 霊璽 means.  Usually jmdictdb contains these kinds of prefixes, but this one was missing.

I only really care about definition [1], which is what is relevant here, but [[2] imperial seal] is clearly in the daijisen.  Given all the other terms for "Imperial seal", and the fact that the n-grams for 霊璽簿 are almost as high as for 霊璽, I am *guessing* that the "imperial seal" interpretation is rare.  I would not mind if it were not included.
