In the book "Fundamental Techniques in Virology", from about 1970 or so,
there was a description of using LiCl precipitation to precipitate RNA.
You might also look at Aufrey and Rougeon, Eur. J. Biochem 107:303-314,
1980 "Purification of mouse immunoglobulin heavy-chain messenger RNAs from
total myeloma tumor RNA".
