The Web allows us to see which portions of RPP most interest our readers. In practice, the hits on the Data Listings and on the Reviews are almost exactly equal. Clearly people care about both. Listings and Reviews
Public Access to the RPP Database A unique, valuable, convenient access to information in our database. And it is fun to explore!
According to SLAC Library, the Review is the all-time top cited article in High Energy Physics with citations. According to SLAC Library, the Review is the all-time top cited article in High Energy Physics with 25,800 citations. 2nd is Weinberg’s Standard Model paper with 6075
Survey on Big Book December 2000 THE QUESTION: Is having a copy of the full-sized book essential to your work or study? Yes, it is essential. Having the full-size book is useful, but I could live without it. No, I do not need it TOTAL Responses also provided comments
Survey on Big Book COMMENT Many of the people who voted "useful" made comments urging continuance of the full-sized book.

Wild predictions for 50 years from now Fifty years is a long time in any scientific field. The last fifty years have changed particle physics beyond recognition. 1.We may not be here. 2.The theories cannot be conceived today (although extra dimensions go back more than 50 years). 3.The computational power will be beyond our wildest dreams. 4.The field may be non-accelerator based. 5.If we start thinking now, maybe we can think of a good name for our field!
