Series I consists of departmental, instructional, and personal correspondence produced by Samuel. H. Graf in the course of his work for Oregon State. The correspondence is arranged by six-month periods, and within each period it is, in general, alphabetical by company or personal name. Topics addressed within the correspondence include inquiries by Graf for gifts of new equipment and engineering literature and publications for use in the Department; responses to technical questions concerning testing techniques; and the completion of commercial tests by Oregon Agricultural College-including accompanying reports and data. This series also contains reports of the activities of the Experiment Station as well as correspondence between Graf and past engineering students.

Series II consists of materials collected by Graf that document the work and activities of the Pacific Coast Gas Association. These materials include meeting notices, correspondence, publications, and research reports. Research topics included internal corrosion of gas mains, pipe protection, and oil processing. The series also contains materials related to an Oil Washing Plant. These include general log forms and data, correspondence, and lecture outlines. Additional correspondence and lecture material describe use of the chemical naphthalene as a pesticide. Of special note is a publication titled the "Gas Engineer's Handbook" which was produced by the Pacific Coast Gas Association. The series contains correspondence related to this publication as well as other booklets and pamphlets presenting the research findings of the Association. Samuel H. Graf was the chairman of the Committee on Pipe Protection, a subcommittee within the Pacific Coast Gas Association.

Series III consists of reports, notebooks, publications, radio transcripts, correspondence, and speeches related to the research and activities of the Experiment Station and Department of Engineering. Topics documented within this series are diverse and include English literature, engineering equipment and product analyses, and the demand for engineers during the 1950s. This series also contains two certificates received by Graf.

Series IV consists of laboratory notes, data, and logs for tests and experiments performed by engineering students during the 1909-1918 and 1922-1923 school years. These experiments occurred in the Cement, Highway, Structural Materials, and Hydraulics engineering labs and analyzed the efficiency, quality, viscosity, and/or impact resistance of various materials and machines. Experimental topics included steel, cement, and steam testing; density and viscosity assessment of oils; examination and calibration of gages; cross-bending testing in timber; compression testing; heating value and proximate analysis of coal; coefficient of friction assessment for lubricants; pressure testing; and engine comparison analyses.

Also included within this series are experimental engineering course listings, reports, and responses to reports.

In addition to a summary of the State Technical Services Act of 1965, Series I contains memos, meeting minutes, reports, and handwritten notes documenting the activities of and future planning for the University's Technical Services Committee. This series also contains reports and correspondence concerning the proposal for and establishment of the Act.

Series II consists of reports, proposals, newspaper clippings and correspondence that describe the impact the Technical Services Act (TSA) would have on Oregon State University and the way in which it would be implemented. The correspondence is arranged, in general, in one year increments and was in large part sent between the State Department of Planning and Development and the OSU Technical Services Committee. Proposals in Series II contain estimates of the costs and benefits of the University's participation in the TSA and outline possible departmental goals and plans for future developments under the Act. Also contained within this series are signed agreements between the State Department of Commerce and OSU describing the University's participation in the TSA as well as documents related to planning for a Technical Services Information Center.

Series III contains correspondence, reports, publications and proposals related to the State Technical Services (STS) program. Correspondence and reports relate to the status of Technical Services Act Projects, transfer of funds between departments, and proposals for funding submitted by these departments. The report , produced as three volumes in 1966 by the Department of Commerce, is included in Series III. This series also contains a five-year plan for the University's participation in the STS program which describes the departments involved and proposed projects, including budgetary information.

Series IV contains annual reports from 1966, 1967, and 1968 documenting the programs conducted under the State Technical Services Act in the State of Oregon. Report topics also include the discontinuation of the Technical Services Information Center Project in 1967 due to lack of funding and time and the status of projects conducted in the fishing and food processing industries.

Series V contains a progress report of Technical Services Act Projects in the fishing and food processing industries for the fiscal year July 1968 - June 1969.

Series VI contains three bulletins offering guidelines and describing requirements for writing State Technical Services Project reports. The first bulletin is titled and was produced by the U.S. Department of Commerce in 1966. The second and third bulletins are respectively titled and .

Series I consists of three lists of Engineering Experiment Station publications issued in 1972, 1974, and 1975 and a 1980 update. The lists provide the titles, authors, and dates for the Engineering Experiment Station Bulletins, Circulars, and Reprints. The 1980 update also indicates which publications are out-of-print. The materials in this series were previously designated as PUB 8-34b.

Series II consists of 62 publications prepared by Engineering faculty or administrators. The primary purpose of the circulars was to distribute compilations of useful data. Most (48) of the circulars are available online in ScholarsArchive@OSU via the links below. Five of the Circulars (nos. 47-58) are only available in paper form. Seven of the Circulars (nos. 1, 5, 7, 12-15, and 20 are only available on microfilm. All of the Circulars numbered 1-30 are available on microfilm reel 32. The circulars were previously designated on PUB 8-33a.

Series III consists of 61 publications written by Engineering faculty to disseminate the results of original investigations. Most (46) of the publications are available online in ScholarsArchive@OSU via the links below. Seven of the Bulletins (nos. 45, 47-50, and 54-55) are only available in paper form. Seven of the Bulletins (nos. 5, 7-8, 17, 23, 34, and 37) are only available on microfilm. All of Bulletins nos. 1-39 are available on microfilm reel 33. Bulletin no. 2 is available in both paper form and on microfilm. These items were previously designated on PUB 8-34a.

Series IV consists of reprints of papers written by engineering faculty and published in professional journals and conference proceedings. The purpose of the Reprints Series was to give more general distribution to scientific papers or reports published elsewhere. The reprints include papers written by F.O. McMillan, R.E. Summers, G.W. Gleeson, B.F. Ruffner, O. Levenspiel, James G. Knudsen, and others. The individual reprints, including article title, author(s), date, and journal title are listed in the Engineering Publications Lists (Series I above). Most of the reprints are only available on microfilm (reel 32); one of the reprints (no. 12 - Water-Wise Refrigeration) is available in paper form in box 1. These items were previously designated as PUB 8-32a.
