You can use `cl-pushnew' for pushing lists as well! As in: (require 'cl-lib) (defvar bird-list-all) (defvar bird-list-1) (defvar bird-list-2) (setq bird-list-all '()) (setq bird-list-1 '("Western jackdaw" "European goldfinch")) (setq bird-list-2 '("rook")) (cl-pushnew bird-list-1 bird-list-all) ; (("Western jackdaw" "European goldfinch")) (cl-pushnew bird-list-2 bird-list-all) ; (("rook") ("Western jackdaw" "European goldfinch")) Birds and Elisp! That, I didn't see coming! Check out this file: https://dataswamp.org/~incal/BIRDS It even has some Elisp to compute the number of observed birds ("kryss", as they are called in Swedish). I have 61, that means not much of an ornithologist, I'm afraid :$ :) -- underground experts united http://user.it.uu.se/~embe8573 https://dataswamp.org/~incal
