This book has synopses for 73 popular operas by 27 composers. There's a short bio of each composer, and a little background info on each opera, like the date of the premier and maybe the original cast. Unfortunately the table of contents isn't active, but it never is in these free books. The free sample should show you the entire table of contents so you can see which operas are included. This book is the 12th edition, published in 1897, but the author's preface is dated 1885, so that must be why there's no Puccini. This book is a good reference for someone who is new to opera.
