The algorithms in some of the pdfs here are not expressed in Algol60 and will be removed. The intention of this collection is to be a resource for transcribing the Algol code in the pdf files to both publication syntax that matches as closely as possible both the original syntax from the CACM papers, and a machine syntax which can be compiled. The Algol60 parser included as a demo with my 'uparse' parser (for Unicode sources) is now a better way to canonicalise Algol60 sources, and has options for outputting versions in both syntaxes - publication and machine. The earlier "algolps9" program should now be discarded. The main sources of scans are: http://bitsavers.trailing-edge.com/pdf/acm/collected_algorithms_from_acm/ along with https://digital.library.unt.edu/ark:/67531/metadc1026054/m2/1/high_res_d/4610211.pdf
