1) Harary's book is great - and he's a hoot. 

2) Ringel and Hartsfield's Pearl in Graph Theory is great, lovable and has lots of pictures and excellent exercises - ideal for an undergrad class that's not geared towards prepping students towards a grad course. 

3) Gross and Yellen's book is probably the best introduction if you're a "mature" math reader and want to really learn stuff - this is what I would buy.

4) Applied Combinatorics by Tucker is phenomenal - but graph theory is only 4 chapters out of 11. Nonetheless, I'd strongly consider this one.

What introductory book on Graph Theory would you recommend?
I have a site to develop. This site is a kind of voucher code site. Means this site will provide voucher codes for other sites. User will come to my site and pick voucher codes for an  another site and will then redirect to that site. In short, it does not need any add-to-cart functionality of magento. 

An example site is shown below in link:  http://www.myvouchercodes.co.uk

However, this site require a strong admin side for support and I believe magento has a strong admin. This is the reason why I am planning to choose magento for my site. So my questions are

1)Is it good to use magento for developing such non e-commerce sites

2)What are the best practices that should take care of when developing such sites using magento

Please share your thoughts... Thanks in advance
