I found some PHP scripts at Saratoga-Weather.Org, a site maintained by Ken True that I used to capture National Weather Service RSS weather forecast feeds. These were great and sure saved me a lot of time! This site is of real value to anyone developing a weather-related web site. Later I decided to access forecasts directly from the NWS using their XML formatted direct feeds.

Listatmatic is a great source for example HTML code you can use to design navigation and menu systems. The code comes with clear and concise explanations about how lists and CSS can work together.

The centered drop-down horizontal menu in this site was inspired by Art and Design by Mathew James Taylor. This is a great site that should be in every web designers bookmark list.

Did you notice the colored separator stripes in all the archived data tables? The code for that came from an article by David Miller in A List Apart.

Dr. David Robinson, Director of the Office of the New Jersey State Climatologist gave me permission to include the 'Current Conditions' page from the ONJSC website. The National Snow and Ice Data Center let me embed their daily sea ice extent visuals. Dr. Tony Phillips from Space Weather gave me permission to use his graphic images in my solar sunspot page. I feel that these additions have made my site more well-rounded and useful.

I constantly referred to these books concerning HTML, CSS and web design.

Learning Web Design by Jennifer Niederst Robbins.
Web Designer's Reference by Craig Grannell.
CSS The Missing Manual by David Sawyer McFarland.
HTML5 The Missing Manual by Matthew MacDonald.
Even More Excellent HTML by Timothy Gottleber and Timothy Trainor.

The last book was used in an online HTML course I took that was taught by Prof. Verno and offered at Bergen County Community College.

I found three books that have been really useful while learning PHP.

PHP in a Nutshell by Paul Hudson.
PHP Hacks by Jack D. Herrington.
PHP The Good Parts by Peter B. MacIntyre.
PHP Cookbook by David Sklar and Adam Trachtenberg.
This last book has really become well-worn since I bought it... it contains hundreds of short code snippets and clear explanations.
