<div dir="ltr">I think you've got it right, that is, no punctuation between the two titles. According to dcrm:b 1F1.2. (italics added by me) "By different persons or bodies. If the individual works are by different
persons or bodies, or the authorship is in doubt, precede each title other than the
first by a period and one space, <i>unless a linking word or phrase is already
present.</i> Precede each statement of responsibility by a space‐slash‐space."</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Oct 27, 2021 at 1:29 PM silvanan <a href="http://mptek.net">mptek.net</a> <<a href="mailto:silvanan@mptek.net">silvanan@mptek.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

Hi there,</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)">
I'm not sure whether to use a period or semicolon (or no punctuation) to separate the 2 titles contained in this book, appearing on the tp as: Romancero gitano / Federico Garciìa Lorca y De la tradicioìn a las vanguardias / Juan Vadillo (authors' names precede
the titles on tp). This is not a rare book, but I believe they would receive the same treatment using RDA. There is no "y" connecting the titles on the cover.</div>
