If the selection of new releases was similar, whether a "brick & mortar" library or a traveling library, why wouldn't you use the traveling version and not have to deal with as many users crowding the premises?
Would it surprise us how what we consider a "small payment" today would compare with a "small payment" back when Encyclopedia Britannica, World Book Encyclopedia, etc. were our main source of reference?
Do you know I have memories of exactly where the Encyclopedia Britannica volumes sat in their bookcase and I used them many times to assist with school work.
