LINK to Online Catalog of the NATIONAL WATCH & CLOCK LIBRARY Vistors to this website are invited to use the ONLINE CATALOG [click on link above] where you can find information on over 10'000 horological books. Searchable by author, title and keyword. VCRs and DVDs are included in the main catalog. Note that the periodicals collection, the catalog collection, the manuals collection, the clippings files (called Vertical files) and the volumninous archives collection is NOT part of the main catalog. The online catalog will tell you if the library has multiple copies (they do for most common titles), which means NAWCC members can borrow the titel through the mail for a low postage cost. .
