I never dog-ear pages — it destroys the fibers of the page — but I rarely go out of my way to buy bookmarks because I tend to forget them inside the book I’m reading. I have a small pile of freebie bookmarks, too — my sister collects for me from various counters in Singapore, I get a lot of bookmarks from the annual Manila International Book Fair, and a lot of BookMoochers send bookmarks too (aside from the official Bookmooch bookmarks)
When I don’t have a bookmark on hand, I can pretty much use anything thin enough to slip in between the pages — a tissue, an old receipt, clothing labels, or I commit the page number to memory, so I really don’t need to buy bookmarks.
Once I interviewed someone for an article I was writing, and I completely forgot that I used his business card as a bookmark! I’d turned my bag inside out, and rifled through my work desk looking for it because I needed to get back to the person I interviewed, and it wasn’t until a couple of nights later that I remembered I had tucked it inside the last book I finished. Hehe. After that, I’ve been careful not to use business cards (or cheques) as bookmarks.
On a visit to one of my favorite book sale branches last week, I chanced upon some great bookmarks at really great prices, and I couldn’t resist getting some. I ended up buying two books (for mooching, none for me) and a whole bag of assorted bookmarks!
