What puzzles me is that the MB often quotes the Ba'er Hetev verbatim - and w/o any citation!
Mah nafshach! If the MB assumes one has no access to the BH and therefore quoted it, then why did he print it on the page?!
And given that the BH IS printed on the page, why bother to repeat it? Why not just cite "ayein Ba'er Hetev"?
And given that the MB does reproduce the BH, why no mention of it as his source?
