From Eric: Prospero 1.26 is out. New features include "conversion of a single page number, or a range of page numbers, from an Ariel document into individual PDFs, for removing the invoice that sometimes comes with an Ariel document or when several documents come in a single Ariel transmission. [Prospero also] now allows import from a monochrome PDF/TIFFs uncompressed or compressed using a CCITT Group3/4 Fax compression scheme."
as seen at freshmeat: "User interface changes, including early support for variable window sizes, smoother pagination, etc. Executable renamed from gutenbook.pl to gutenbook." see gutenbook.org for more.
the Simon Fraser University Library Research Instrument (SLRI) is "a web to Z39.50 client interface" brought to you by the good folks at SFU. it's an adaptation of the web to Z39.50 gateway developed by Harold Finkbeiner at Stanford, licensed under GPL and recently spied at sourceforge.net as well.
