A very good book.

If you want to hear the case for Open Source

versus the free software movement and versus closed-source commercial software,

get this book.

Raymond puts forth his case strongly and clearly.

The book marks a turning point in the history of Open Source

and is worth reading on that basis alone.

On the other hand,

If you want a book that gives many different Open Source positions,

I suggest reading

"Open Sources: Voices from the Open Source Revolution".
