A few months ago I refurbished the Software Preservation Group website, and the museum moved it to a subdomain of the main web site:
Also, the projects/ subdirectory was dropped. The Museum's IT folks set up redirections that work for top level things. So:
correctly redirects to:
But unfortunately not all the "content" URLs redirect correctly. So for example this item in the Zotero bibliography:
http://www.softwarepreservation.org/projects/LISP/bbnlisp/TenexLispRef_Jul71.pdf
should be changed to:
https://softwarepreservation.computerhistory.org/LISP/bbnlisp/TenexLispRef_Jul71.pdf
If someone could make me a list of "old style" URLs in Zotero, I'd be happy to send back a corrected list.
