Pirs wrote thousands of Ginans, many of which are lost.
600 of them were recovered and published in the Ginan compilation by Mukhi Lalji Devraj's the Khojki Printing press.
Ismaili Manuscripts are still being found with unpublished Ginans.
A few are linked below.
Some examples of possibly unpublished ginan titles can be found in the Heritage Society's partial Khojki Manuscript catalogue: http://ismaili.net/heritage/node/23075
