Dear Thomas,

I am using databases for  long time is the best idea to have field like:

mycode  [10]    Rc-056-133 [ this file help to me sort database fylogenetica=
ly]
codegebien [5]  number sensu Gebien catalogue of Tenebrionidae
Family:  [50]   Tenebrionidae
Subfamily: [50] Tenebrioninae
Genus:   [50]   Strongylium
Species:        [50]    umbrium =3D
synonym_of: [50]        viridis
bracket1:        [1]    (
author: [50]    Fabricius
author_yea: [4] 1799
bracket2:       [1]     )
page    [8]     568-570
Refcode         [6]     KAS-456 (reference number to relate with database of papers=
 and references)
Area    [10]    NEOTROPIC
Distribution: [120]     Brasil
note    [120]   this could be valid specie !!., type locality unknon.

Notes:
You have to sometime sort the database to check if you do not make misspe=
ling, etc.
Despite using Access I prefer to write database in dBase IV, thank to com=
mand "CARRY ON" and "Insert". It save typing.
*.dbf database is large, but can be accepted by any other databases inclu=
ding spreadsheets and wordprocessors.
