The set of encyclopedias could be measured by the number of volumes it contains. Alternatively, you could measure it by the total weight of all the books combined.
Some popular printed encyclopedias that are still available and suitable for the average reader include the "Encyclopedia Britannica," "World Book Encyclopedia," and "Encyclopedia Americana." These encyclopedias provide comprehensive information on a wide range of topics in an accessible format for readers of all ages.

Encyclopedia is singular, encyclopedias would be plural.
Most encyclopedias are arranged alphabetically by subject. If you can't find what you need, consult the index volume.

Not much really. Just the fact that the "free encyclopaedias" are actually FREE. The other encyclopaedias you are talking about, I assume would cost money, and they would usually contain more information depending on what brand you purchase and if the sources are reliable (you trust them).
Sure. Online encyclopedias are still encyclopedias. And if you do not have a computer available, the book form is still quite useful.
