Do you accept a non-Eplain solution :) ?  The following does
not use Eplain and works as long as you don't have any text
after the final \form in a paragraph:

====================CUT====================
% Punctuation between two \form's.
\def\formpunct{; }

% Finish off with a period and reset \par.
\def\newpar{.\endgraf\let\par\endgraf}

\def\form#1#2#3{%
  \leavevmode % Ensure \everypar takes effect.
  \punct
  {\it#1\/ }#2 #3%
  \let\punct\formpunct
  \let\par\newpar
  \ignorespaces
}

\everypar={\let\punct\empty}% No punctuation before the first \form.


\form{name}{year}{source}
\form{name}{year}{source}
\form{name}{year}{source}

Some other paragraph.

\form{name}{year}{source}
\form{name}{year}{source}
\form{name}{year}{source}

\form{name}{year}{source}
\form{name}{year}{source}

Some other paragraph.

\bye
