Dating an album

Google is your friend.

:-)

Do you mean looking for the release year?

Try Discogs. Make sure you have the Matrix / Runout numbers (in the deadwax) for each LP in question as this will help in pinpointing which release it could be as there can be many.

OK the label information is usually found at the record company site or there are internet resources that would supply the info about record label release years. Also discogs.com can often have a release year information of a particular album if found and if there.

While browsing my wardrobe, I also came across such CDs. Was there anyone willing to share links to old music fanatics?

I think it's important to read the right blogs for a broader outlook. For example bagnolodipo.com there are many articles on this topic. This blog helped me to understand many issues.
