Do your shelves look like this? After every class visit, I walked around the library straightening dozens of shelves that looked just like this. Although the bookends had a cork bottom, it did little to prevent book slides after a few books had been removed.
Here’s a hot tip I learned from my colleague and fellow librarian, Cathleen: glue kitchen cupboard liner to the bookends.
I am so fortunate to have Sandi, a parent volunteer, who took home countless bookends over the summer, and used a caulking gun to affix shelf liner to them all.
This method works SO well to prevent slippage, that it is actually a little difficult to shift the books over when re-shelving. That’s a trade-off I don’t mind at all.
