Change to how we box journals from Internet Archive

Hi Everyone,

For those helping with the pulling and boxing project from Internet Archive:

From now on, all boxes with journal volumes should be marked "J." As always, do not mix them with books. Never mix any codes.

To summarize, here are the labels we will use from now on:
Books have 1 of these 3 (you can tell which code it is from the sheet).
D
F
S

Journals are J

Note that this does not apply to books and journals coded for recycling/discard, which don't get boxed.

Let myself and Nick know if you have any questions and thanks.
