Hi Chris Whotsit
Welcome to stamps! You'll probably find the stamps aren't worth much in cash - but in real terms any decently varied collection is priceless, a wonderful way of finding out more about our amazing world.
Most UK libraries will have or can get Stanley Gibbons Simplified catalogues - alphabetic listings of the whole world in 5 large volumes. The latest year they have will be for reference use only, but they often have earlier years that you can take home.
A book that I think is definitely worth getting hold of is The Stamp Atlas "(A unique assembly of geography, social and political history, and postal information) (Hardcover)" - via
Amazon from about £5 including delivery,
Amazon listing at
http://www.amazon.co.uk/gp/offer-li...ndition=usedIt gives a lot of historical info and sample stamps for the whole world, and is great fun to dip into.
And as you get to know what you have, you'll find what most grabs your fancy - and then arrange it how you like, there are no rules in stamp collecting. Lots of useful advice on storage methods etc in this forum - and as several members have said, we're always happy to share what we know. It's an amazing hobby!
