You would also find a lot of discussion of contracts for software and services in the ADPASO archives at CBI. https://archives.lib.umn.edu/repositories/3/resources/286 ADAPSO was a trade organization which began with service bureaus and diversified into software. Helping its member companies produce contracts was a significant focus of its operations, and it produced model contracts of various kinds for their use, eventually leading to a Contracts Reference Directory. Many years ago I worked with these papers to produce a short series on its history in IEEE Annals.

The query is fairly broad so time share, leases, procurement contracts across contexts are very welcome :) I wish to look at the evolution of vendor restrictions (if any, although i think there would be ?)
