Luckily the library has lots of books for helping with these tasks, since preserving and canning fresh foods is not something I do on a regular basis. I'm only just learning how to freeze certain foods, and the library has books to help me with that too. Great websites that offer tips and recipes for preserving foods are www.mealtime.org and sustainablepantry.com, but to me, nothing beats having an actual book I can hold in my hand and refer to when I get lost.
Some great books on storing foods to check out at the library:
