Perhaps you should try some spelling variations:
information documentation » international documentation, information presentation, information documents
protocol definitions » protocol descriptions, protocol functions, protocol examinations
protocol defining » protocols defining, protocols designing, protocol learning
libris » xlibris, libri, libros
