Wasting my time?

I've assembled all this information about 1970s beers. Enough to do something like the brewery section of the Good Beer Guide. But with the bottled and keg beers included.

Is it weird to do a guide the past? For a lost world? Though I have done all that stuff about the DDR. There's a whole country that's gone forever.

Here's what an entry might look like.

Am I wasting my time?
