Adding a new data source

[Pau Garcia i Quiles]

Hello,

I would like to add the Book Database from the Ministry of Culture of
Spain ( http://www.mcu.es/webISBN/tituloSimpleFilter.do?cache=init&prev_layout=busquedaisbn&layout=busquedaisbn&language=en
) as a new source. It contains more than 900,000 references by ISBN
(every book published in Spanish since 1972).

AFAIK this database does not use any standard protocol, so I would
need to make HTTP POSTS and GETS and parse HTML. I have seen fetchers
should inherit from Tellico::Fetcher::Fetch and implement a few
methods. I was wondering if there are any special rules or advices I
should follow.
