These two foundational texts—A Guide to Fortran Programming by Daniel D. McCracken (1963) and Programming With FORTRAN IV by Byron S. Gottfried (1972)—offer detailed instruction in one of the earliest and most influential programming languages. McCracken’s guide, widely used in the early years of computer science education, covers the basics of FORTRAN programming with clarity and structure, emphasizing both syntax and practical application. Gottfried’s work, focused on the FORTRAN IV iteration, builds on that foundation with updated examples, exercises, and technical depth, making it especially useful for those studying legacy systems or the history of programming languages. Together, the books provide insight into mid-20th century programming logic and remain relevant for historical study, archival work, or niche programming interests.
 
Both books are softcover and in good condition. A Guide to Fortran Programming shows light shelf wear but no writing or markings. Programming With FORTRAN IV contains some highlighting but remains fully readable and intact. Please see photos for further details on condition.
