Photocopies and microfiche of trial transcripts, trial exhibits, depositions, legal memoranda, motions, subpoenas, and other documents relating to U.S. v. IBM, Control Data v. IBM, Greyhound Computer Leasing v. IBM, Telex v. IBM, CalComp v. IBM and IBM v. Catamore Enterprises. The transcript of the trial proceedings and the collection of court exhibits provide a record that brings together a wealth of detailed documentary evidence on the electronic data processing industry in the 1960s and 1970s.

Technical research priorities, product development decisions, marketing and sales practices, and maintenance and service arrangements for many firms in the computer industry are to be found in the trial record. Much of the voluminous evidence presented by both parties was drawn from IBM's internal correspondence and files. Many other systems and components manufacturers also presented testimony. The court documents additionally incorporate extensive hearing transcripts, testimony and memoranda concerning important legal and economic issues, e.g., measurement of market share, pertinent to the case and to antitrust law in general. Some items are missing from the collection. Many documents and exhibits, however, were presented as evidence in more than one of the cases and documents not found in one trial's record may be located in another trial in the collection.

The impact of these antitrust cases extends beyond the computer or data processing industries. These cases have generated much debate about questions raised by monopoly charges -- the definition of market share, the distinction between competitive and predatory behavior, and the problems associated with prosecuting the charge of "intent" to monopolize trade. As these issues are likely to be the focus of important discussions among jurists, economists, and many in business, the documentary evidence contained in this collection will be valuable resource for those interested in this crucial aspect of American business.
