Usage notes

Most senses of information are uncountable. The legal sense, referring to court filings, is one that does form a plural. Using the plural form when one of the uncountable senses is meant is generally an error made by non-native speakers. A grammatical alternative would include a counter word as in pieces of information or bits of information.
