This section of the site is built around a database which includes specimens, information on provenence, collections and references.
The core of this was collated by Tracy Ford, and I have built extensively on the basic information he provided. The database itself is a complex relational database made in Microsoft Access, and for technical as well as practical reasons I keep this as a off-line resource. The web pages are now created from a mySQL database which can be updated either on-line or from the master database, which means that the process of updating is far quicker than the old, off-line method.
The following sections of the site are run from the database:
The section called 'Old Texts' is a collection of papers and other documents made available on-line and does not form part of the database.
