The Design Patterns in OOP e-book is available

The object technology website 
 Objects.cz
 has made the e-books DESIGN PATTERNS in OOP and RDB Persistor available. The author
 of both books is Ilja Kraval, RNDr. I’ve had DESIGN PATTERNS in OOP for more than a year
 and it’s one of the core textbooks I heartily recommend for studying design patterns and OOP.

To get the books, just send an email to 
 objects@objects.cz with the subject line ‘zadam o dokumenty zdarma’ (‘requesting free documents’). See more information about downloading the books.
