Most of these resources focus on the current thinking around author promotion, indie publishing, and some of the seismic changes currently taking place in the book publishing sector. I will also be recommending a number of book titles focused on helping authors to improve their writing on my Book Review pages.

The Self Publishing Podcast – YouTube
Three US based sci-fi/horror authors who work collaboratively with one another to write their books and figure out how to effectively promote them. The Youtube channel they have – SPP is packed full of really useful advice and insights and is generally released once a week with an additional once a month ‘Ask Us Anything’ session which attempts to answer questions sent in by viewers.
It’s not really possible to mention the SPP without also mentioning the ‘Worst Show Ever’, which is generally recorded and released straight after the SPP. This podcast generally has very little to do with writing, and is more about the same three guys just making fun of one another and talking about life away from the keyboard. It routinely features strong language, bad taste humour an abundance of self mockery, so possibly not for prudish or faint hearted.

Creative Penn – http://www.thecreativepenn.com/
Another indie author (Joanna Penn) this time UK based with a very informative YouTube channel https://www.youtube.com/user/thecreativepenn. Slightly less rambling but still nice and light hearted, Joanna is another font of information and experience, and routinely interviews other movers and shakers on the scene.
Joanna Penn is also one of the founding members of the Alliance of Independent Authors along with co-founder and co-presenter Orna Ross. ALLI also have a video blog, which like the Creative Penn is often very informative about new developments in the sector as well as changes in best practice ALLI on YouTube

The Self Publishing Roundtable – SPRT Website
Another really useful and often really entertaining video podcast, this time by a larger group of individual indie authors, who take it turns to make up the panel, which often results in a different blend of insights and perspectives on the wider industry – participants include authors that write and read in a wide range of genre’s including romance, erotica, fantasy, sic-fi, urban fantasy, young adult etc.
While there are several full time authors on the SPRT, there are also several who are still only writing part-time while they build up to going pro.
SPRT also launches frequent box-set collaboration projects and other initiatives.

Science Fiction and Fantasy Marketing Podcast –
Yet another really useful video podcast this time featuring the same three indie authors based in the US, all a different stages in their career including a part-time author, a recent full-time author and well established full-time author.
Unlike the others, the the SF&F is more narrowly focused on the marketing and promoting of indie books, and in particular on books written within the science fiction and fantasy sub-genre’s.
This podcast regularly features guest interviewees, Question and answer sessions and general news about the sector – Science Fiction and Fantasy Marketing Podcast on Youtube

Neilsen – http://www.isbn.nielsenbook.co.uk
At the other end of the scale, there’s Neilsen. For anyone not already aware Neilsen Books are one of the main providers of book data in the world, and also happen to be the ISBN agency for the UK (i.e. the folks you can buy ISBNs off if you’re interested in forming your own publishing house.)
Now while the content on Neilsen is focused on the established industry, if you’re prepared to wade through the site there are some gems inc this white paper on the link between metadata and book sales (by metadata they mean things like a good cover, author bio, the book blurb on the back cover etc)
