PyCatalog is another app that's been mentioned here before but doesn't have a local tarball cache. thebestfemdom The last version I can find on sourceforge is 1.3, which has these release notes.
From the writeup on the home page: "pyCatalog is a Python, MySQL, wxPython, Reportlab application specifically usable in library and information centers. It simply produces book catalog and card catalog in pdf format rendered using reportlab. The program takes MARC file as its source data. pyCatalog - is a combination of Python, wxPython, Reportlab, and python-mysql application that renders Book and Card Catalog."
Tarballs of the linux build and source for 1.3 are attached.
