NZVRS Library <<<back to NZVRS homepage
The NZVRS maintains a fairly extensive collection
of radio related material under the tender care of the NZVRS Librarian, Ernie Hakanson. However the library is always on the lookout for
any radio related circuit information - especially early
Circuit information from the library collection is available to members at a minimal copy fee. It is possibly best to communicate with Ernie first to get a quote on the cost and availability of the information sought before sending your request and cheque. All cheques should be crossed "Not Transferable" and made out to the NZVRS.
The NZVRS Librarian's contact details are;
Sorry due to
Ernie’s sudden death the NZVRS Library will remain closed until the end of
April 2008.
All correspondence
should be forwarded to the main contact for the NZVRS or email:
office@nzvrs.pl.net;
An article copy
service is available as follows;
Copies of the following articles are available from the library at the fee of $1 each item, plus $1 post and package per order. [Applicable section of the NZ Copy Right Act 1994]
