This review is from: Ancestral Trails: Complete Guide to British Genealogy and Family History (Hardcover)
This is the Bible of British genealogical research! It is extremely comprehensive and the invaluable references (in the bibliography) are numerous to say the least.
It took me a while to appreciate as it appears a bit daunting at first, however once you give it a go it opens up new possibilities for sources you previously wouldn't have considered and describes them in astounding detail.
I would class this book as suitable for intermediate to advanced researchers however it can be used by a beginner with a little effort.
