Dream Valley - Getting the ID to your ponies would be complicated and difficult if it wasn't for this site! Kimberly has a step by step process that lets you very easily identify almost every My Little Pony evermade.
The My Little Pony Collector's Website - A great reasource with many pictures of ponies and their related items MIB or MOC. Tons of information!
Be aware that Euro ponies were released with different names than their US counterparts, and many US ponies were released with the same names. For example there is a Euro flower pony Daffodil and a mail order birthflower Daffodil, three newborn twins named Sniffles, two named Snookums and two sets of Rattles and Tattles. I mention this because when negotiating a trade, buy or sale over the net where no picture has changed hands, always, ALWAYS, try to include a desciption of the pony with symbol color and year and set of the pony in question. It saves a lot of confusion and time. Make sure when writing up your want and trade lists to also include this info, ex: 'yr 5 Newborn Sniffles, pink/mittens'.
