where can i find information on good spells?

Ultimately good spells are the spells you write for yourself.  
Learning that is the best idea.
So..........
Janet and Stewart Farrar books are excellent.

Since I suggested you write your own.  Here we go.
Sit down and think about the reason you want a spell.
Then ask for the Goddess you work with and the God you work with to be available for guidance.  Have a pad of paper and pen/pencil and start writing the intent of what you want.
Then start thinking about the energy needed to accomplish.
Think about the energies that exist at the time you want to do the spell.
Is the moon growing? new? full? decreasing in size?  You want to use the energies to help you, if possible.  
Are you able to yell, scream, jump, dance? to build energy?
You want to build into to your rite to do the spell, a way you are going to build energy to get what you are trying to create.
Are you wanting to use candles, you need to have what you want to dress the candles.  You need to gather the tools you may need and maybe make an altar.
Then as you are doing this, what do you want to say.  Doing something you can chant that rhymes is often good, if not for the Gods, definately for you.
Then keep it simple, Go over and over what you are wanting to have and what you are making for yourself.  Are you manipulating or controlling someone else?  (you really don't want to do that, double check and make sure you aren't creating a problem for yourself or someone else if you are including or making your spell about someone else.)
After you have gotten everything ready to where you are sure it's the way you want it. Start your rite and do your spell and then LET IT GO!!!! Know it is done.  

Yes, you can do ritual bathing before, if you are in a place to do that.
You can have all the bells and whistles you want and enjoy.
You can have none and it just be you in your rite with the Gods and Goddesses and elements.  That is up to you.

Have fun, even if it is serious.  Be loving.  And yes have reverence.  

Take any bit of this and use it if you want, or throw it all out.  What's important is the spell you want must be as much yours as possible, it must be within your ethics and integrity, even if you find something on the net you want to use.

Blessed Be.

That is the best, up front, honest bit of advice on spell work I have ever seen on a web forum :D

gene, thank you. I

Hi Giggle,

Good spells thou are seeking

First Giggle, "What would you like to do with these "spells?"

And second, "How simple would you like them to be?"

These things can be done.

Love!
