There are at least two important guides for records collector:

RARE RECORD PRICE GUIDE published by the well known english review Record Collector and
GOLDMINE PRICE GUIDE TO COLLECTIBLE RECORD ALBUM.


RARE RECORD PRICE GUIDE GOLDMINE PRICE GUIDE TO COLLECTIBLE RECORD ALBUM

The first one is specialized in records printed in UK, the second one in records printed in USA. Both guides are useful not for the quotations but for the labels descriptions. It is not necessary to get the most recent ones just because the labels didn't change. On the new editions we can find at least some interesting update or some 'new entry' ignored in the past.
GOLDMINE is published by Krause Publications - 700 E. State Street - IOLA WI 54990-0001 - USA
RARE RECORDS PRICE GUIDE is published by Record Collector - 43/45 St. Mary's Road - EALING, LONDON - W5 5RQ - UK.
To find out one copy of RR isn't difficult because you can order it directly at Record Collector, the most competent review talking about collectible records and it's easy to see it at the Records Fairs. Less easy for Goldmine, but both can be found in the web at Amazon or Ebay.


Another very useful guide, full of discographies and lines up is: ROCK RECORD written by Terry Hounsome. This is the seventh edition.

The most important guides printed in France are: LA DISCOGRAPHIE DU ROCK FRANÇAIS written by Francis Grosse and Bernard Gueffier published by: Musea - 138, Rue de Vallières - 57070 METZ - FRANCE- and LE ROCK PSYCHEDELIQUE AMERICAIN 1966-1973 - printed in two volumes by Èditions Paralleles - 47, Rue Saint - Honoré - 75001 PARIS - FRANCE.


LE ROCK PSYCHEDELIQUE AMERICAIN VOL.1 LE ROCK PSYCHEDELIQUE AMERICAIN VOL.2 LA DISCOGRAPHIE DU ROCK FRANÇAIS



For the European Rock in general, we can't forget two guides printed at the end ot the eighties by the japanese Marquee's: ENCYCLOPEDIA OF EUROPEAN-ROCK - 1966-1987 and ENCYCLOPEDIA OF BRITISH ROCK.
The first volume describes the european artists discographies, with the lines up and some pics of the era taken by the well known italian review Ciao 2001. Unfortunately comments are written in japanese. Very competent book that mentions Janus (Al Maestrale) in the italian groups discography, Flute & Voice (Imaginations of Light) in the german one and Book of AM in the France one.
The second volume it's about the English Rock and the covers records pics are in full colors like the pics of the groups. The authors mentions Michael Nyman with Zakarrias in the progressive section: probably when they came in Europe to empty the records shops, they paid all the same price :-)
Anyway they are two very good books.


ENCYCLOPEDIA OF EUROPEAN-ROCK - 1966-1987 ENCYCLOPEDIA OF BRITISH ROCK



For the lovers of the family trees the right guide is The Complete Rock Family Trees printed by Omnibus Press and distribuited by Book Sales Limited - 8/9 Fifth Street - LONDON W1V 5TZ - ENGLAND.
