This article provides a reasonably good description of various voting
methods, as they're defined on EM:
http://www.9mail.de/m-schulze/votedesc.pdf

The section on Bucklin agrees with how I've understood it: it's a ranked
method where you stepwise add in first, second, ..., kth rank until
someone attains a majority.

Due to Bucklin's LNHelp feature combined with a lack of LNHarm leads to
a natural idea of letting voters instruct Bucklin to "skip ranks" on
their ballots. This in turn leads to majority grade methods like MJ.

(The article is wrong about supplementary voting being a form of
Bucklin, though. It is a two-step IRV.)
