/sys$common/syshlp/helplib.hlb CMS, SHOW, LIBRARY, Qualifiers, /BRIEF  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The /BRIEF qualifier displays the directory specification (and
    does not lock the library) even if the default library is locked
    by another user. However, if the library needs recovery, it is
    not detected until another operation is performed.
