From the "z/OS v1r6.0 JCL Reference Guide":

http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2B650/19.0?DT=20040712170508

Quote:

The JCLLIB statement allows you to code and use procedures and INCLUDE groups in a private library without the need to use system procedure libraries.


From the same manual:

http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2B650/13.2?DT=20040712170508

Quote:

Use the JOBCAT DD statement to define a private VSAM or integrated catalog facility user catalog for the duration of a job. The system searches the private catalog for data sets before it searches the master catalog or a private catalog associated with the first qualifier of a data set's name.


Again, same manual:

http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/IEA2B650/13.4?DT=20040712170508

Quote:

Use the STEPCAT DD statement to define a private catalog for the duration
of a job step. The system searches the private catalog for data sets before using the normal order of catalog search. In other words, the system searches the private catalog for data sets before it searches the master catalog or a user catalog associated with an alias matching the high-level qualifier or qualifiers of a data set's name.

For what it's worth, a PROCLIB is usually the term given to a library (PDS or PDS/E) where cataloged procedures are stored. Some typical PROCLIB names are 'SYS1.PROCLIB' or 'PROD.PROCLIB'.
