Aimee,
From what you've said it would be hard for anyone to know what you are offering of use to anyone. If you have a hoard of pamphlets, perhaps you could start by reducing what you have by tossing outdated pamphlets in the recycle bin, except for a few which may have historic value. You haven't made it clear enough what you have that you think may be of use to others. Please be more specific.
I'm fine with what I posted. The list is long so I'll need time to go through it all. It's hard to find the time...
I did say animal & veg topics, so for a slightly narrower idea: factory farming and veganism. However, I also have ones for side issues.
*sigh*
With your feedback in mind, I forfeited sleep to go and have a look

I also have a box of "Why Vegan?" booklets that I paid for.
Hey Glen, I'd really like these to be placed in to people's hands while leafleting or running stalls. Leaving them at a veg restaurant is probably preaching to the converted, and plastering them on uni noticeboards will generally get them either removed or ignored.
You're right, they would be perfect for a weekend market stall or even a Farmer's Market, if someone has a little bit of space on their table for passersby to take a look.
