How to know what library an LSC item came from

If a DUL item was moved from a campus library to the LSC, it can be helpful to know what library the item came from.

Historically, this has been understood from the naming of the LSC collection code, specifically the letters that the code starts with.

PSB = BES
PSC = Chem
PSD = Divinity
PSG = Docs
PSL = Lilly
PSZ = Marine
PSM = Music
PSK = Perkins
PSV = Vesic
