The publishing house announced it would be dropping 19 of its
journals associated with a publisher they had acquired, in part
because they infested with fake papers.
前面的"publishing house"和"publisher"应该是不一样的，
但中文的翻译好像都是出版社或出版商，那差别在哪里？
还有" with a publisher they had acquired "的"they"是指什么？
是指publishing house? 但前面代名词已经用单数it
还是指 journals ? 那要"...had acquired"要怎么翻译理解？
以上请教 谢谢大家

查一下定义蛮简单的

一般来说应该同义，在这篇应有"规模"的差异(前大后小)they: 指前者"publishing house"it: 一样指前者had acquired: 大出版社收购小出版社连同其出版品
