A method of providing a user access to data files distributed in a plurality of different types of user devices is described. The catalyst used in the process comprises a source of palladium and a source of a phosphine characterized in that at least one substituent on the phosphine is an ortho substituted aryl group. The process includes spelling normalization, lexical normalization, and pronunciation conversion. Other embodiments are described and claimed. The light source module includes: one or more light source units including a light emitting element emitting light when electricity is applied thereto; and an optical sheet disposed above the light source units and exhibiting bidirectional transmittance distribution function characteristics having first and second peaks at radiation angles less than 0\xb0 and greater than 0\xb0. and a melt enthalpy change \u0394H of from 40 to 70 mJmg as measured with a differential scanning calorimeter; and the allyl glycidyl ether in the ethylene oxide-propylene oxide-allyl glycidyl ether terpolymer being in a copolymerization ratio of from more than 10 mol % to 20 mol % or less.
