I love libraries, I borrow books all the time, even cookbooks. It's my way of try-before-you-buy. Try the recipes in the books first before I buy the book. It is a bit hard when you only have three weeks before you need to return the book, but my library allows me to renew the loan once, so I can actually have the books for six weeks.
The latest book I borrowed was this amazing cookbook by Antonio Carluccio called 100 Pasta Recipes. Eventhough Antonio is one of the greatest Italian cooks of all time, the recipes in this book are not pretentious, some are even very easy to do. I have tried three easy recipes so far, and I have added all three of them to my weekdays meal repertoire.
