<i>Prachum Pakaranam</i> ("Collection of Tales") is a book series in which ancient Thai tales of foreign origin are compiled, published by the Wachirayan Royal Library. The present volume consists of the following:
<ol><li>A preface by Prince <a href="https://en.wikipedia.org/wiki/Damrong_Rajanubhab" class="extiw" title="w:Damrong Rajanubhab">Damrong Rachanuphap</a>, dated 25 December 2467 BE (1924 CE).</li>
<li><i>Wetalapakaranam</i> ("Tales of Vetāla"), a group of tales found in a manuscript obtained by the Wachirayan Royal Library. Its author(s), date of creation, etc, could not be ascertained. Its source is apparently the Sanskrit scripture titled <i><a href="https://en.wikipedia.org/wiki/Baital_Pachisi" class="extiw" title="w:Baital Pachisi">Vetālapañcaviṃśati</a></i>, which Prince <a href="https://en.wikipedia.org/wiki/Damrong_Rajanubhab" class="extiw" title="w:Damrong Rajanubhab">Damrong Rachanuphap</a> believed had been known to the Thai since antiquity. Anyway, the prince found that only the final part of this work corresponds to the Sanskrit scripture, whilst the initial part is completely different from the Sanskrit scripture.</li></ol>
