Interlibrary Loan (ILL)
The UPSE Library offers ILL to users who want to borrow books from partner libraries. Email upselibrary.upd@up.edu.ph to avail.
Referrals
If ILL cannot be used to borrow the needed material/s from a partner library, the librarian can provide a referral letter to the user so s/he can personally visit the partner library and photocopy the material/s needed.
