Our records are kept mostly in the form of what's called the "Board Pack." The president and board AA prepare this document before every board meeting--it contains reports, committee summaries, proposals, minutes, and more. If you're interested in digging through our history, Board Packs are absolutely the place to start.
Only those with an @bsc.coop email account can access the archives, however. If you're a manager or board member, then you should have no problem. If you're a member, ask one of your managers or board members to let you browse the archives. If you're not a BSC member, email the president at firstname.lastname@example.org about the records you're interested in and they'll go about getting them to you.
