Top software development books

Jurgen Appelo at noop.nl created another great list...the top 50 new software development books. The list includes books covering various aspects of software development: project management, business analysis, user experience, testing, refactoring, agile practices, architecture, web services, etc. The list was created using a weighted list of the following criteria and includes books that are less than two years old...

• Number of ratings on Amazon.com
• Average rating on Amazon.com
• Number of ratings on GoodReads.com
• Averate rating on GoodReads.com

Note: The time that has passed since a book's release date was part of the calculation. For example: A book that got three 5-star ratings in just four months is listed higher than a book that got the same ratings in a much longer period of time
