Loan Objects Database (loanobjects)
The Loan Objects database is an intermediate database used by the Circulation module to group copies under a single bibliographic title to apply loan policies efficiently.
Purpose
In ABCD, loan policies are often applied to "Objects" (Titles) rather than individual copies. This database facilitates the display of all available copies for a specific title during the loan process.
