A library or a systematic collection of books, often used as part of formal library names.
From Greek biblio- (book) + -theke (storage case/repository). The term was Latinized and became the formal term for libraries, especially in European institutions.
When you see 'Bibliotheca' in a library's official name, you're looking at a word that connects to 2,000 years of institutional knowledge preservation—from ancient Alexandria to modern archives.
