Further to my last post, I have located another 9 freely available volumes of the English Reports. The bibliography is now missing volumes 42, 68, 74, 83, 101, 112, 117, 127 and 165, due to Google, Hathi Trust and Internet Archive not having digital copies; volumes 170 to 176 are missing as although Google have copies, the full text is not being made available, presumably due to copyright issues. In all, just 16 volumes, around 9%, are absent from the full set of 178 books.

I have also adapted the table of the reports archived in the Wayback Machine, to include links to the individual volumes. This provides a convenient way of locating material by original publication, and by the abbreviations generally used to refer to them.

Update, 11 May 2021: As pointed out in the comments, Common LII hold a full set of the Engish Reports, broken down into single PDFs. I don’t find their database particularly easy to search or browse, though: some reports appear misfiled under the wrong date, and the PDFs often have fragments of other cases included, which means searching often throws up false positives. The OCR, as ever, also leaves something to be desired. Nevertheless, it is the most convenient, complete and openly accessible set available.
