The East End Nobody Knows by Andrew Davies 1990. ISBN: 9780333474549
Came across this intriguing book about the East End of London in my local library. It includes histories of the local areas (Whitechapel, Almshouses in the East End, The Battle of Cable Street, etc.); how places got their names (Isle of Dogs, Bethnal Green, etc.); and character highlights (Matchgirls and Dockers, Joseph Merceron, an East End Boxing Champion, etc.). The book covers very early times to 1980s in a condensed fashion. The part I like the best is at the back where a number of East End historic walks are included (the author used to take tourists on 'off the beaten track' walks).

A guide to the Lloyd's Marine Collection and related marine sources at Guildhall Library. Declan Barriskill. £4.95 ISBN: 9780900422553
This little guide is invaluable to anyone researching marine ancestors. Although it seems to highlight the marine sources at the Guildhall, much of the content applies to any library that holds Lloyds collections. For example, it is useful for definitions and coverage of the Lloyd's Register, Lloyd's List and Lloyd's Captain's Registers. You can order it via the Guildhall Library website.
