Thanks to the effort of our Librarian, Frits van Beekum, the contents of the PPS library are now available online as a spreadsheet, to make it easy to search and sort books, catalogues, and periodicals by author or title. You can use the ‘Download as’ option in the ‘File’ menu to copy the spreadsheet to your computer in a variety of formats. If you are a PPS member, you may contact the Librarian to obtain a document held in the library.
