A few days ago I was at a Half Price Books store. Something which struck me at the moment was that while there were probably 20 Perl books (some of them duplicates), there wasn't a single Python book. I took it as in indication that Perl is in decline and people are unloading their personal perl library and nobody is buying the used ones; meanwhile, people are holding on to their Python books and ones which show up get snapped up. The alternate interpretation is that Perl needs a LOT of books to explain things due to its quirky syntax and myriad coding idioms, so there are simply more Perl books in circulation.
