The following guidelines are used when marking volumes for Valesio
- Mark on Yale bookplate when there is one, generally in the upper left corner.
- Mark on verso of last page, lower right hand corner, when there is no Yale bookplate. The lower left hand corner is the alternate location when the lower right hand corner is unusable.
- If the last page is unmarkable (e.g. too dark or shiny or filled with text or illustrations), mark the verso of the first usable page from the end.
NOTE: Do not mark call number on original wrappers.
