Spell it “iBrary,” and I wouldn’t even blink. I’d just assume it was Apple’s answer to ebrary for the iPhone and iPad. But unless I’ve missed something, Ibrary is still just a typo for library. You’ll find it in the high-probability section of the Ballard list, and there are 14 entries in OhioLink with this error.
Some are simply typos. But others represent spelled-out acronyms for series (e.g., N[ational] h[ome] l[ibrary] ) and are therefore intentional, if not necessarily correct. Either way, they're obstacles to searching, and in your own catalog you might at least consider providing access to the text string sans punctuation if you don’t want to do full series authority work.
