This list is not a recommendation of languages that you should learn or use (see [1] for that. The majority of the languages on this list are languages that i don't know but want to learn.

Please note that my intention here is not to be comprehensive (see if you want that), but rather to list only those languages that i consider to be of particular interest. 'Of interest' usually means that either this is one of my favorite languages to use, or that i think that a language has something to teach about programming language design (which has not yet been generally absorbed, e.g. i've heard that Lisp invented if-then-else, but by now everybody is familiar with that construct), or that i want to learn it.

Some books and links to learn about these languages

As above, these are mostly things i want to read, not things i've read.
