Do you use bookmarks? And if, then what are you using?  

I always use book marks as I can't abide people who turn down the corners of the pages. I respect my books and I like to pass them on to other people. I even give a bookmark with them. I often buy nice bookmarks and whenever I run short of them I use a little picture or some notepaper. I definitely won't borrow books for buy secondhand books after reading your topic. Yuck!

OMG! How disgusting! I have to say I would NEVER even contemplate taking a used panty liner and using it to mark my page! LOL

I have used some odd stuff but (cover your eyes since you are a librarian) I more often then not, when I don't have anything around, will dog ear the book. Yes, yes, I know.. bad reader! LOL

I've used pictures, bills, napkins, straws, you name it.. but never anything disgusting like a used pantiliner for sure! LOL

when i do use a bookmark when i do read. Its either a real bookmark i bought from a store, or its usually a small piece of paper or something that size. LOL i bet that was a very interesting find in a book.

Ewww that is disgusting! Yes I use bookmarks. I have several that are metal that was given to me as a gift. I also have a few that are cardboard. I have been known to use a receipt from a store if I didn't have anything else. I don't think I have ever used anything weird or odd.

I always use a book marker of some kind but only when I'm not at home. I use a book pillow. It is the neatest thing. It has straps that hold your book open. A pocket for my reading glasses and a ribbon for the book marker. I came across the book pillow at http://geocites.com/havefunwithgenealogy
The lady that makes them is a genealogist. There is a link on her site for the book pillow. She will also make one for any room in your house if you want it to coordinate with your decor.

I use a bookmark. My hubby used to work in a library and would go mental if I bent the corner of a page. My current one is of Queen Nafratiti from Egypt.

I ahve several actual book marks,but they never seem to be where I am when I need the. So I will use a small piece of paper, but a used panty liner is just too gross.

Since I can't stand bending the pages back to book mark my spot. I will use a book mark, a playing card, once I even used a piece of string. I have never used money or anything disgusting. I treat my books with a lot of respect, and I find it very hard for me to lend my books out to anyone. Fear of them not being returned or being returned with so many creases it's not even funny. I have also taught my daughter about using a book mark when she's reading that way her books will look new when her sister begins reading.

I use all kinds of things as bookmarks, however nothing as extreme as feminine products. I use business cards, receipts, post-it notes, scrap paper and so on. Sometimes I'll fold over the corner of the book if I don't half a 'usable' bookmark within reach.

eugh - I do use strange things as bookmarks and as a second-hand bookseller have come across some interesting things. I use corners of newspaper, old shopping lists, at the moment I am using a dustwrapper from 'The Tale of Mr Todd' as a bookmark in the Harry Potter book I am reading to by children for their bedtime story. In books I have sold I have found, a cheque, various bits of paper, letters, postcards but no banknotes unfortunately.
