Im first year phd, and a conference I attended (and wrote a full length paper for) is organising a book from it and was invited to submit a chapter.
My supervisors say not to bother, as papers are worth far more, but I feel weird turning down an opportunity, and I understand papers are difficult to publish - I feel what I did was fine, but its not like...ground breaking, my baby, that I only want to publish in a certain place if you know what I mean.
I'm new to all this and don't really understand the REF system or anything so would appreciate advice!
