NEW YORK -- Billionaire Mayor Michael Bloomberg is sharing what he has learned in business and government in a new book due out this year, The Wall Street Journal reported recently.

Bloomberg, who founded a multibillion-dollar company and then became an internationally known mayor, is penning the book, titled "Do The Hard Things First (And Other Bloomberg Rules for Business and Politics)," to be published by Vanguard Press. It will be his second book, after his 1997 autobiography, "Bloomberg by Bloomberg."

Bloomberg's wealth is estimated at more than $11 billion, a fortune he built after founding the financial-information empire that bears his name. He stepped down from the company to run for mayor in 2001 but retains a 68 percent stake in the company.

The 66-year-old, who is in his second term, had been considering an independent run for president this year but said recently he had decided not to. The lifelong Democrat became a Republican for his mayoral run but last year became an independent.

Bloomberg will not get an advance for the book and is donating all royalties to the World Trade Center memorial foundation.

Ten years after his death, Frank Sinatra just goes on and on. The man, the myths, the music -- especially the music -- are undimmed. To commemorate the anniversary, there's "Remembering Sinatra: 10 Years Later" (Life Books, $19.95), a glossy scrapbook of Sinatra lore.

The book includes a remembrance by fellow crooner Tony Bennett, a reprint of Gay Talese's classic 1966 Esquire profile, "Frank Sinatra Has a Cold," and scores of photographs, including those by John Dominis, who tailed the Rat Pack for Life magazine in the late'60s.
