The Big Book of Lego Facts

It's my first LEGO book, honestly. I had to buy it, 'cause I'm a Copy Writer and it helps me a lot, but there are things that bother me. There is no any information about Spiderman, so in that case I had to use YouTube and see what LEGO fans had to say. Next: Index at the end of the book doesn't offer many search options. For an example: I was looking for word "Pegasus" and there is no such a word in Index. 'Cause of that I hat to search it myself, page by page, which takes time and I have found two pages that have a description about pegasus.... Or, when I was looking for LEGO "Friends" sets, I found them myself on pages that were not written in the index...
