PHP - Web/list Question...

Hi. I've got a question/issue that I want to bounce off the list. I have a list that extends over multiple pages. there might be 200 items, and i don't want to have the items listed on the same page as it would be too long. i can break the list up, so i can have it be displayed over multiple pages. however, i want the user to select different items from the list. given that the selected items might be over different pages, what's the best way of keeping a running track of the items that have been selected?? I could have each page be a form, and do a post/get where i then keep track of the selected items from page to page, but that would appear to get ugly. i'm looking for pointers to other sites/code that might have already implemented this kind of scenario. thoughts/pointers would be appreciated... thanks
