Categorizing the text-only pages

[MarcoP]

If there is a historical factor I'm not considering which meant that 1v would typically be written immediately after finishing 1r, please correct me.

I am not an expert, but in manuscripts that can be read the text that begins on 1r is typically continued on 1v. See for instance the online transcription of You are not allowed to view links. Register or Login to view. or of  You are not allowed to view links. Register or Login to view.. I take this as evidence that 1v was written immediately after finishing 1r.

Also, the mostly blank page You are not allowed to view links. Register or Login to view. in the VMS should have been in the "recto" position, according to your system.
