HD made an error as an inanimate object cannot be infallible, but it can be inerrant (which the Bible is)

I disagree. Since "infallible" is an adjective and adjectives describe nouns or pronouns, the Bible can certainly be called infallible. According to "Aunt Merriam":

infallible - 3 dictionary results

in·fal·li·ble   /ɪnˈfæləbəl/ [in-fal-uh-buhl] –adjective

1. absolutely trustworthy or sure: an infallible rule.
2. unfailing in effectiveness or operation; certain: an infallible remedy.
3. not fallible; exempt from liability to error, as persons, their judgment, or pronouncements: an infallible principle.

That seems right to me, too, dear sister in Christ.
