I'm a sudent at the moment with the good fortune to have cash to spend on books and access via university and work to various on line resources. I've realised that there isn't a simple answer to this one.
ADB is fine for 'more common building situations'.
BS 5588 is quite old now and some of it is quite outdated (Part 10 for example)
DD 9999 is new but has some major weaknesses in my opinion. It works for fairly straightforward buildings but kind of struggles with things like warehouses/mezzanines for example.
The definitive BS has to be 7974 - the engineering standard. It deals with all the issues from a 'first principles' perspective - how comprehensive do you want???
In terms of books, I've got fire dynamics books (which won't really do the job for you), the SFPE Handbook and NFPA Codes (all from USA) but they're all huge and convoluted. I've also got 'Buildings and Fire' by T J Shields which is a bit old now.
Using Barbour indexes I've got hold of copies of 2 other books:
'Means of Escape from Fire' by Billington, Ferguson and Copping (published by Blackwell)
'Design Principles of Fire Safety' by the Dept of the Environment (300 pages, published in 1996 and written by Bickerdike Allen)
If it's an affordable simple book you're looking for you could do worse than 'Fire - Design from first principles' by Stollard and Abrahams. It roughly follows the process of ADB. I've included a link to Amazon just so that you can see the cover. I paid under £20 for mine.
http://www.amazon.co.uk/Fire-First-Principles-Design-Building/dp/0419242708The LPC Guide is good but looks at the problem from a property protection point of view.
Another book I've found very cheaply recently is 'Evaluation of fire safety' by various authors including Rasbash, Ramachandran and Law. Again a google search and a look on Amazon found me what should be a £90 book for £16 including post and packing! Bargain!
Other than that you could ask around to find people with older copies of books/standards that have been superceded and are no longer required?? As Led Zeppelin once said, the details may change, but broadly speaking 'the song remains the same'!!
