Our By-laws state that it is the Board Secretary's job to "keep an exact and permanent record of the proceedings of the Board of Trustees."  So, our Board Secretary takes the minutes at our meetings.  With that said, we also have our administrative assistant take notes in case the Board Secretary needs to confirm/clarify something when typing up the minutes.  I personally think it's important that the Board Secretary be responsible for those anyway... that's generally the description for most Board Secretary duties... plus, I wouldn't want it to appear that the library/library staff were "skewing" anything in the minutes if there was something that the staff might feel differently about than the Board.  I want it to be an accurate representation of the Board's stance on whatever was discussed.  We won't edit them, either, when the draft is submitted.  Any changes/corrections to the draft minutes (even typos) are done at the next Board meeting before final approval..... just to make sure everything is done transparently.
