The Trinity 3.0 Arrangement (T3) of the Sraffa Papers is an archival architecture which structures the vast material and provides a road map rendering it conducive for scientific study. Sraffa’s archive is in fact a rich and complex mosaic of inter-connected note-sets. The T3 arrangement organizes Sraffa’s literary remains in two important ways:
Section D3/12 of the Sraffa archive contains notes on Production of Commodities by Means of Commodities consisting of over 7000 mostly handwritten pages in 115 files; to data the T3 arrangement has been made for the material in section D3/12 of the Sraffa Archive that dates from 1927 through 1932.
The T3 arrangment is an organic interface combining the note-set character of the text as first identified in the Bharadwaj-Garegnani (BG) inventory from the mid to late 1980s with the Wren Trinity (WT) catalogue from the early 1990s.
Readers can find here an article written by me, Professor Scott Carter of The University of Tulsa, published (2019) in the online peer-reviewed journal American Review of Political Economy, that describes the history of the Sraffa archive and the development of the arrangement (then called Trinity 2.0) using as an illustration the single file folder D3/12/3: Notes London 1927 (Physical Real Cost, etc.). This was the file that Professor Garegnani subjected to scrutiny in his seminal 2005 Turning Point article. Garegnani’s knowledge of the BG inventory allows him to introduces the first hybrid convention between the BG inventory and the WT catalogue, serving as the prototype for the Trinity 3.0 arrangement.
In terms of meta-file organization, T3 puts the files in chronological order (excepting the first two files which are outliers). This requires a reshuffling of files from the WT catalogue and the breaking-out of 5 of the Bharadwaj-Garegnani files, three BG files from WT.D3/12/10 and two from WT.D3/12/9. This gives a total of 16 T3 files as opposed to the 13 WT files from the period. To keep matters as clear as possible, each file folder will be identified by all three conventions, T3, WT, and BG.
