Gather your collection and take your books one by one and wrap them in a plastic bag, trash bag, or some other protective covering to avoid wetness / stains and stick them in the freezer. The coldness will get rid of any smells and kill any pests and their eggs in the same breath. I recommend starting with your largest and oldest books first, more so if they already had silverfish problems already and if you bought them online, at garage sales, used bookstores, inherited them, or otherwise come from sources that contain silverfish. Make sure to keep the frozen books away from any possible contaminated books. If the problem continues, You can also dust your books, bookshelf and possible entryways with Diatomaceous earth and Boric acid or set up some homemade or store bought traps in the future. I almost always throw used books I buy in the freezer as soon as they come home to get rid of possible smells and pests.
KEEP IN MIND that freezers do not kill mold but only stop it's growth for a day or two after being taken out of the freezer, you're going to have to vacuum and clean every infected page yourself.
