Template talk:CategoryList

How to eliminate double entries?
I tried to use this to make a list of books in a subject, like this: However, it listed every book twice, firstly the book page itself, and then the book category, like this: category=Python programming language

suppresserrors=false shownamespace=false ordermethod=categorysortkey order=ascending Is it possible to fix this, or is there a better template to use? --InfantGorilla (discuss • contribs) 15:58, 31 January 2012 (UTC)
