Merging two people's libraries can be as fraught as merging their lives

Fadiman opens by describing the years-long delay before she and her husband, both writers, finally combined their separate book collections into one shared library, a process that forced constant small negotiations about duplicate titles, organizing philosophy, and whose copy of a shared favorite would survive the merge. The delay wasn't laziness; it reflected genuine anxiety about what combining libraries would mean for each person's sense of independent identity within the marriage.

She treats the eventual merger as a meaningful milestone in the relationship, arguing that seeing your books interfiled with a partner's, no longer separable at a glance, is a concrete symbol of a shared life in a way that other more obvious markers of commitment sometimes aren't.

Fadiman is candid that some incompatibilities never fully resolved, including differing philosophies about whether books should be organized by subject or by some looser personal logic, and that the couple simply learned to live with those small unresolved tensions. Takeaway: how two people choose to combine their books can be a genuine test, and expression, of how they combine their lives.
