Resources for 50s/60's programming lore?

Looking for suggestions/resources on where to look into understanding commentary about old programming references (notes circa 1950's / 1960's)

aka. could use row on punch cards as "page number" to machine sort dropped group of punch cards, which at 2 ^ 7 gave max ~127 index references.

For higher order number of punch cards & simpler/less expensive sorting, use felt tip marker to add lambda mark along side of block of punch cards.
