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.

Before that, why not post some pictures here, but only of stamps pre-1943;or if after 1943, stamps with a face value of $5 or more (or the equivalent amount in foreign currency). Stuff after 1940 or so, with rare exception, has little value used and only a percentage of face value if unused.

Except for some old stamps that are expensive, most valuable stamps are varieties of other stamps. Software that identifies stamps, in many cases, cannot discern between the cheap and expensive versions. And it tends to suffer from bias towards the expensive varieties. So, in addition to such software, you, still, will be needing a good catalogue.

There is a very high probability any software that identifies stamps will get this one wrong:
