Question    
How to open a new EXTnn library?

Answer    
It’s not expected to add new EXTnn libraries, and there is a check in the “Open a new library” script which avoids adding such a library. However, it’s possible to open a new EXT library following these steps: 

(1)    Change the following line in script $aleph_proc/open_new_library_checks: 
from 
set template_libs_list = {uni,usm,ext,utf,vir,mab,usr} 
to 
set template_libs_list = {uni,usm,utf,vir,mab,usr} 

(2)    Add the library  to $alephe_root/aleph_start (sample library is ext40 here) 
       setenv    ext40_dev          ${ALEPH_MOUNT}/a${ALEPH_VERSION}_$ALEPH_COPY 

Change:

       setenv    DEMO_LIBS          "$DEMO_LIBS ext01 ext02 ext03 ext04"

To:
       setenv    DEMO_LIBS          "$DEMO_LIBS ext01 ext02 ext03 ext04 ext40"

Do "source aleph_start".
