It doesn't make sense as written. 100 = cien; 'libro' = '(a) book', or 'I deliver'; 'la biblioteca' = 'the library' If 'libro' were 'libros', '100 libros' = '100 books', but no specific connection is suggested with 'la biblioteca' ('the library') If you are trying to say "There are 100 books in the library." the Spanish is "Hay ciento libros en la biblioteca."
