Who it’s for

Owners of personal and small community libraries who lend books to family, friends or members. Admins manage the catalogue and loans; members sign in to browse the catalogue and see their own loans.

When thousands of books are lent informally, it is easy to lose track of who has which copy and when it is due. FLEX Library keeps a catalogue of titles and copies, records every checkout and return, and flags overdue loans.
