Software Advice

I'm looking for a way to store and organise Web Links and / or Web Pages in one place on my iMac so that I can categorise them into different headings. I'm collecting numerous links and it has become a necessity to reference them with greater ease. If there is a software solution that links with an iPhone that would be even better.

Thanks to all who take the time to look and offer advice.

The bookmarks feature of Safari does everything you're asking for. Do you need something over and above that?

Bookmarks is an obvious choice that just escaped me. Sometimes the simplest solution is right in front of you. I would prefer something that would allow notes to be attached and have been wondering about Evernote. Thoughts anyone?
