+Therefore, @command{tar} provides a special mode for creating
+multi-volume archives.
+
+@dfn{Multi-volume} archive is a single @command{tar} archive, stored
+on several media volumes of fixed size. Although in this section we will
+often call @samp{volume} a @dfn{tape}, there is absolutely no
+requirement for multi-volume archives to be stored on tapes. Instead,
+they can use whatever media type the user finds convenient, they can
+even be located on files.
+
+When creating a multi-volume arvhive, @GNUTAR{} continues to fill
+current volume until it runs out of space, then it switches to
+next volume (usually the operator is queried to replace the tape on
+this point), and continues working on the new volume. This operation
+continues untill all requested files are dumped. If @GNUTAR{} detects
+end of media while dumping a file, such a file is archived in split
+form. Some very big files can even be split across several volumes.
+
+Each volume is itself a valid @GNUTAR{} archive, so it can be read
+without any special options. Consequently any file member residing
+entirely on one volume can be extracted or otherwise operated upon
+without needing the other volume. Sure enough, to extract a split
+member you would need all volumes its parts reside on.
+
+Multi-volume archives suffer from several limitations. In particular,
+they cannot be compressed.
+
+@GNUTAR{} is able to create multi-volume archives of two formats
+(@pxref{Formats}): @samp{GNU} and @samp{POSIX}.

+To create an archive that is larger than will fit on a single unit of
+the media, use the @option{--multi-volume} (@option{-M}) option in conjunction with
+the @option{--create} option (@pxref{create}). A @dfn{multi-volume}
+archive can be manipulated like any other archive (provided the
+@option{--multi-volume} option is specified), but is stored on more
+than one tape or disk.
+
+When you specify @option{--multi-volume}, @command{tar} does not report an
+error when it comes to the end of an archive volume (when reading), or
+the end of the media (when writing). Instead, it prompts you to load
+a new storage volume. If the archive is on a magnetic tape, you
+should change tapes when you see the prompt; if the archive is on a
+floppy disk, you should change disks; etc.

+@table @option

+@itemx -M
+Creates a multi-volume archive, when used in conjunction with
+@option{--create} (@option{-c}). To perform any other operation on a multi-volume
+archive, specify @option{--multi-volume} in conjunction with that
+operation.
