         <p>It is a pleasure to preface
          Paul Tres&#39; latest edition of his seminal work <i>Designing Plastics 
          Parts for Assembly</i>. The enduring popularity of this work is due 
          not only to Mr. Tres&#39; thorough exposition of his subject matter, but its
          extreme ease of reference and lucid prose. A well&#8211;written treatise in any
          technical field is welcome, but one in the design and manufacture of plastics
          parts is essential for today &#39; s manufacturing economy, where plastics parts are
          assuming roles once thought impossible for man&#8211;made materials.</p> 
		   <p>The fact that this book is 
		   now in its Fifth Edition speaks for the usefulness of a text that 
		   clearly presents the basic principles of plastics parts manufacturing 
		   and design and then illustrates these principles with timely and well-conceived
		   case histories. The case histories draw directly from Mr. Tres&#39; 
		   extensive experience as a top consultant in the field of plastics for 
		   a Who&#39;s Who list of multinational clients. In these comprehensive 
		   illustrations, Tres applies the basic principles introduced by his 
		   reference book to cutting edge subjects such as press fittings, living 
		   hinges and snap fittings, essential to the palette of any parts designer.
		   It is in these case histories that Mr. Tres&#39; gift as a teacher and as 
		   a designer shines through. The result is a work that lends itself to the 
		   classroom, as a classic reference and as an aid to the practicing design engineer.</p> 
		   <p>The clear exposition and 
		   organization of Paul Tres&#39; book makes it immediately useful to both 
		   the accomplished expert and the novice layman. I have used the book in
		   preparation for complex patent litigation on matters related to the 
		   manufacture of plastic parts. In my experience, the simple organization and
		   helpful illustrations made the book an ideal choice for explaining complex
		   technical issues related to the manufacture and design of plastics parts to a
		   lay jury.</p> 
		   <p>Likewise, the book lends itself to
		   any application in which complex issues of plastic manufacture and design
		   need to be concisely and accurately conveyed. In addition, the book is not
		   short of intellectual rigor and lends itself equally well as a reference 
		   text for the accomplished technician and academician.</p> 
		   <p>Recommending the text is an 
		   easy task for me, but my introduction is superfluous, since the 
		   text speaks for itself.</p>
