Books needed for SL

[brain122]

I know I have seen some discussion on this, but could not recall where.

I thought it might be a good idea to start a thread that would be easier for people to find.

Can people respond here on the book situation for SL?

i.e. did you use library books, purchase from them, online resources only?

and for what classe?
i.e. econ I and econ II..........purchase of books necessary or not?

Thanks for the info.
