The shelfmark fields(#800 to #80R) are all used in the same way, and can all take the subfields described below where necessary. Subfields are entered in no particular order, and are not repeatable.
The field #80V, which records details of the Van der Loon books, is used differently and explained separately.
#800 Sinica 6041
If a work is not kept in its customary or expected location, but has been moved to a reading room or a special storage area, its permanent shelfmark is entered first, followed by its actual location after " = ":
#800 Chin.e.265 = Z.C.400.1
#806 Chin.e.41122 = C 9548 YJ Ref
#800 Backhouse 578 = Arch.O.d.46
The most frequently used subfield is subfield |c, for copy notes. This subfield contains information relating to our particular copy, not the edition in general. For example, the copy may be a later printing. Notes on the condition of the copy are also entered into this subfield - it may be incomplete or damaged, or we may have changed its binding, or bound it with something else:
#800 Sinica 6486|c書品劣
#800 Sinica 6301(1)|c與「碑別字補」合訂為洋裝1冊
Copy notes in old books may be used to point out how second and subsequent copies differ from that described in the bibliographical record:

The software supplies the first part of the URL that leads to the text (currently http://iiif.bodleian.ox.ac.uk/iiif/viewer/).

#800 Sinica 4129|pV|gs02126.jpg:s02127.jpg:s02128.jpg:s02129.jpg
To date (20 April 2016) only three letters have been used:

|V||Van der Loon|
If a book (usually a pre-modern one) is part of a historic collection and has a number (usually a catalogue number), this is recorded in subfield |s:
