This is very much down to personal preference. The articles in this book are few in number and not wildly helpful. I have no vested interest, just prefer the W&A yearbook, which I've bought previously and which has better articles. The listings are the same regardless, but for the same money you may as well get the one with the better articles. That said the online facility is useful but could be really developed - for example, to include a 'save list' for agents / publishers of personal interest. This facility could lure me away from W&A yearbook.
