Primary and Secondary Sources About Nicaragua

Here are a few items I've recently come across about Nicaragua worth taking a look at when considering Nicaragua and its historical relationship with the U.S.

Here is a semi-primary source called With Walker In Nicaragua by James Carson Jamison (who went with William Walker to Nicaragua in the mid 19th century).

Here is an unbiased semi-primary perspective by John Pilger about Nicaragua's "unique struggle to end the cycle of poverty and humiliation" -- well, except for the unbiased and unique part.  But if you're into gore or are a Somozista with no reservations, make sure you watch at minute 23 of the video.

After watching that video, it would be hard not to be a Sandinista supporter@!  Except, then one has to wonder, how did Pilger manage to fail to present even one interview with the Nicaraguan opposition - whether that opposition was out of the country, fighting within the country, or living within the country?  I wouldn't have known to ask about that, but after three years when I lived in Nicaragua, I talked to all those kinds of people (as well as the same Sandinista-supporters Pilger interviewed).  Pilger's journalism about Nicaragua has about as accurate a representation as Margaret Mead's experience in Samboa: a packaged misrepresentation that justified some inner psychological need of the artist/journalist/scientist.

I'd like to read some primary sources from the 17th through 19th centuries.  Anyone have some good ones they recommend?
