Readers of this blog may find it useful to be able to link to a certain MS in the List of MSS in the Virtual Manuscript Room (Münster). Martin Fassnacht recently told me that he had broadened this possibility.
The link to use for Papyrus 1 is the following: http://intf.uni-muenster.de/vmr/NTVMR/ListeHandschriften.php?ObjID=10001
It is the last five digits that identifies the specific MS. The first digit represent the type of MS, and the other four the Greg.-Aland number of that MS with zero digits to fill out if necessary:
1 = papyrus, e.g., 10120 = P 120
2 = majuscule, e.g., 20004 = 04 (Codex Ephraemi rescriptus)
3 = minuscule, e.g., 30081 = 81
4 = lectionary, e.g., 41775 = l1775
