All correct. Common Lisp, the topic of this paper, was made an ANSI standard in 1994, but in a less official capacity it's many years older, and of course its lineage reaches the 1950s.
On top of that, within the Common Lisp community, one of the most important transformation happened in 2010, with the release of Quicklisp - the de-facto community standard package manager, which drasticly simplified working with Common Lisp libraries (espetially for beginners). Given all that, and the ongoing community evolution, it really matters what year is a paper about CL library ecosystem from.
