What would be your recommendation for the text which could be useful for someone starting with lattice theory? Suggestion for both books and online materials/lecture notes are welcome.
This was asked as a part of this question and I did not like that it was combination of two different questions. (One of them on geometric modular lattices and the other one about text recommendation.)
I don't expect the user to post a follow-up question, since he was not seen at MSE for some time. I think that this could be a useful for some users here, so I've decided to post it myself.
