		<description>Jason, the books are were all related to computing. Engineering books hold their value better. They also retain their &lt;em&gt;perceived&lt;/em&gt; value better.

There are two issues here. First, some computer books really are worthless after a few years. Second, some computer books are worth reading, but people presume they&#039;re worthless because there are so many books in the first category.</description>

		<description>When you say &quot;technical books&quot;, do you mean specifically computer-related, or technical in general?  Because certainly the autodidact has a lot to gain from a book on aerodynamics from twenty years ago, or a fifty-year-old book on wooden building construction, even though they might be abandoned as school textbooks.</description>

		<description>I like going through antique stores and finding collections of books to see what sort of technical books they might have.  Saw an intro to computer hardware and architecture the other day from 1982.  $9 is too much to be asking for something like that, when it&#039;s not even in mint condition. :P

I usually offer my old tech books on craigslist.  I can almost always get rid of them all that way..</description>

		<description>True, but some books retain their value much better than others. Here&#039;s an interesting exercise: Which of your books might your grandchildren care about?

I would hope that my grandchildren are interested in my copies of &lt;a href=&quot;http://www.amazon.com/gp/product/0895267896?ie=UTF8&amp;tag=theende-20&amp;linkCode=xm2&amp;camp=1789&amp;creativeASIN=0895267896&quot; rel=&quot;nofollow&quot;&gt;Witness&lt;/a&gt; (1952) and &lt;a href=&quot;http://www.amazon.com/gp/product/B000OEA066?ie=UTF8&amp;tag=theende-20&amp;linkCode=xm2&amp;camp=1789&amp;creativeASIN=B000OEA066&quot; rel=&quot;nofollow&quot;&gt;Story of Civilization&lt;/a&gt;  (1963).</description>
