Dr K.K. Seet says: 'Pleasure is generally singular unless one is making a case for a variety of different pleasures. Papers is understood these days to be the abbreviated form for newspapers. All the first sentence needs is to invert the words "provided" and "are" for the sentence to read: "The magazines and (news) papers are provided for your reading pleasure." Since one imagines a number of magazines and newspapers, the pronoun should be "them" rather than "it". Moreover, "premises" already refers to the current space so "the premises" will do, instead of "this premises" which sounds redundant and also ungrammatical.'
