Fonda Lee said on Twitter something like this about books marketing :

"In the long run, the thing that sells books the most 
is word of mouth. 

This goes 10x for books that aren’t launched with big marketing 
or publicity support i.e. 95% of books. 

What I’m saying is, talk up the books you love, 
because their survival depends on it."

That's why I started a serie of Perl books review 😃
(and also for personal notetaking 👍)

So far, here is the list of reviewed books (list always under construction) :

• Perl and LWP
• Perl and XML
• Perl pour l'impatient [FR]
• Perl and DBI
• Perl for System Administration
• Mastering Perl
• Advanced Perl Programming
• Perl Hacks

Want more Perl books ? You can find them on my almost complete list of Perl books

Thank you OReilly. Most recent released books are mainly on PerlSchool
