The 'Library' and 'ReferenceBlock' info from 'libinfo' is very useful, but 'libinfo' does not return as many blocks as find_system. In the case I am working on, find_system returns about 500 more blocks than libinfo. However, none of the block properties appear to be 'Library' or 'ReferenceBlock'. Is there anyway to obtain this? I use get(get_param(handlesReturnedByFind_System, 'handle')) to get block parameters.
Thanks is advance

'ReferenceBlock' is a block property. 'Library' is not. You are probably looking for 'LinkStatus'.
model='f14';
open_system(model)
b=find_system(model,'FindAll','on','type','block','LinkStatus','resolved')
get_param(b,'ReferenceBlock')
ans =
'simulink/Sources/Band-Limited
White Noise'
>> lib=libinfo(model)
lib =
struct with fields:
Block: 'f14/Dryden Wind↵Gust Models/Band-Limited↵White Noise'
Library: 'simulink'
ReferenceBlock: 'simulink/Sources/Band-Limited↵White Noise'
LinkStatus: 'resolved'
If you are asking, in the returned info of libinfo(), where does that 'Library' info come from?
then, it is the file name (or library name) of the library block specified in 'ReferenceBlock'.
>> bdroot(lib.ReferenceBlock)
ans =
'simulink'
