Many firms ,have great difficulty in obtaining books because they are unwilling to have their names entered as having taken out such and such a book .我想知道as在这里的用法,是连词吗,或者介词?新概念的翻译是:因为他们不想让人家记下它们公司的名字和借阅的某一本书.as被翻译成了"和",本人有点理解不了.
新概念是权威的,我想知道准确的解释,一楼你的回答也太没水平了吧.......

可以理解为they are unwilling to have their names entered as they have taken out such and such a book .因为they为逻辑主语,主动（公司借阅的某一本书）,所以可以省略为 as having taken out such and such a book
有表示原因、起因的含义,也有伴随、表时间同步的含义.
