Tonight I came across an interesting website produced by Gary S. Dykes which claims to provide background information on the late Reuben J. Swanson’s process of collating NT manuscripts. Once you get past the colours, the information Dykes provides gives a lot of background on how Swanson worked and the completeness and accuracy of the published collations. Thankfully, he believes that Galatians is one of his most accurate volumes. On the other hand Dykes is quite harsh with regards to the quality of the gospel volumes and claims that Swanson made a large number of errors which made it to press because no double checking by a third party was carried out and his manuscript copies were often of poor quality.
