Software Recommendation To Id, Value And Catalog Collection

We recently inherited a stamp collection from my father-in-law. I'd like to find a good software pkg that can help identify the stamp and catalog it. Additionally a ballpark value for insurance purposes. We know nothing about stamps / so lots to learn. Any recommendations? The stamp collection includes stamps mounted in books ok paper, those in plastic. A lot just loose in a box.

Thsnks in advance for your advice.
